| 1 | Characterization of dissolved organic matter in urban sewage using excitation emission matrix fluorescence spectroscopy and parallel factor analysis显示文摘Wastewater dissolved organic matter (DOM) from different processing stages of a sewage treatment plant in Xiamen was characterized using fluorescence and absorption spectroscopy. Parallel factor analysis modeling of excitation-emission matrix spectra revealed five fluorescent components occurring in sewage DOM: one protein-like (C1), three humic-like (C2, C4 and C5) and one xenobiotic-like (C3) components. During the aerated grit chamber and primary sedimentation tank stage, there was only a slight decrease in fluorescence intensity and the absorption coefficient at 350 nm (a 350 ). During the second aeration stage, high concentration of protein-like and short-wavelength-excited humic-like components were significantly degraded accompanied by significant loss of DOC (80%) and a 350 (30%), indicating that C1 and C2 were the dominant constituents of sewage DOM. As a result, long-wavelength-excited C4 and C5 became the dominant humic-like components and the DOM molecular size inferred from the variation of spectral slope S (300-650 nm) and specific absorption (a 280 /DOC) increased. Combination use of F max of C1 and the ratio of C1/C5, or a 350 may provide a quantitative indication for the relative amount of raw or treated sewage in aquatic environment. | Weidong Guo Jing Xu Jiangping Wang Yingrou Wen Jianfu Zhuo Yuchao Yan | 2010 | Journal of Environmental Sciences2010，22，11： | 36 |
| 2 | A review of polybrominated diphenyl ethers and alternative brominated flame retardants in wildlife from China:Levels,trends,and bioaccumulation characteristics显示文摘Accelerated industrialization and urbanization,and unregulated disposal of waste of electric and electronic equipment(e-waste) in China have caused environmental pollution of brominated flame retardants(BFRs).This review summarized the levels,trends,and bioaccumulation characteristics of polybrominated diphenyl ethers(PBDEs) and other potential alternative BFRs including hexabromocyclododecanes(HBCDs),1,2-bis(2,4,6-dibromophenoxy) ethane(BTBPE) and decabromodiphenylethane(DBDPE) in wildlife from China.PBDE levels in wildlife from China were generally higher than those from other parts in Asia,and were comparable to those from Europe but were lower than those from North America.However,wildlife from the e-waste recycling sites in South China and East China contained much higher PBDEs compared to other reports around the world,suggesting the heavy contamination of PBDEs in these regions.The alternative BFRs were also detected in wildlife,revealing that the animals are exposed to these chemicals,in addition to PBDEs.Temporal trends indicated by levels in marine mammals from South China suggested that PBDE levels increased from the beginning of 1990s to 2000s,but decreased from the middle of 2000s,followed by relatively steady levels.In contrast,HBCDs were found to be continuously increasing from 1997 to 2007,indicating the increasing usage of HBCDs in China in recent years.Compared to PBDE profiles found in other parts,aquatic species and birds from China contained relatively higher contributions of BDE28 and 209,respectively,suggesting the possible different usage pattern of PBDEs.Future works including keeping monitoring at a reasonable scale and frequency to make sure levels near urban centers indicative of population do not increase are needed.Additionally,focus effort on e-waste recycling regions to look for impacts and to determine if regulation/controls are resulting in lower environmental contamination,and incorporation of sentinel species in monitoring efforts are recommended. | Jiangping Wu Ying Zhang Xiaojun Luo Yazhe She Lehuan Yu Shejun Chen Bixian Mai | 2012 | Journal of Environmental Sciences2012，24，2： | 15 |
| 3 | Effects of subchronic oral toxic metal exposure on the intestinal microbiota of mice显示文摘Oral exposure to toxic metals such as cadmium(Cd), lead(Pb), copper(Cu) and aluminum(Al) can induce various adverse health effects in humans and animals. However, the effects of these metals on the gut microbiota have received limited attention. The present study demonstrated that long-term toxic metal exposure altered the intestinal microbiota of mice in a metal-specific and time-dependent manner.Subchronic oral Cu exposure for eight weeks caused a profound decline in gut microbial diversity in mice,whereas no significant changes were observed in groups treated with other metals. Cd exposure significantly increased the relative abundances of organisms from the genera Alistipes and Odoribacter and caused marked decreases in Mollicutes and unclassified Ruminococcaceae. Pb exposure significantly decreased the abundances of eight genera: unclassified and uncultured Ruminococcaceae, unclassified Lachnospiraceae, Ruminiclostridium_9, Rikenellaceae_RC9_gut_group, Oscillibacter, Anaerotruncus and Lachnoclostridium. Cu exposure affected abundances of the genera Alistipes, Bacteroides,Ruminococcaceae_UCG-014, Allobaculum, Mollicutes_RF9_norank, Rikenellaceae_RC9_gut_group,Ruminococcaceae_unclassified and Turicibacter. Al exposure increased the abundance of Odoribacter and decreased that of Anaerotruncus. Exposure to any metal for eight weeks significantly decreased the abundance of Akkermansia. These results provide a new understanding regarding the role of toxic metals in the pathogenesis of intestinal and systemic disorders in the host within the gut microbiota framework. | Qixiao Zhai Tianqi Li Leilei Yu Yue Xiao Saisai Feng Jiangping Wu Jianxin Zhao Hao Zhang Wei Chen | 2017 | Science Bulletin2017，62，12： | 12 |
| 4 | Spatiotemporal patterns of the fish assemblages downstream of the Gezhouba Dam on the Yangtze River显示文摘An explicit demonstration of the changes in fish assemblages is required to reveal the influence of damming on fish species.However,information from which to draw general conclusions regarding changes in fish assemblages is insufficient because of the limitations of available approaches.We used a combination of acoustic surveys,gillnet sampling,and geostatistical simulations to document the spatiotemporal variations in the fish assemblages downstream of the Gezhouba Dam,before and after the third impoundment of Three Gorges Reservoir(TGR).To conduct a hydroacoustic identification of individual species,we matched the size distributions of the fishes captured by gillnet with those of the acoustic surveys.An optimum threshold of target strength of 50 dB re 1 m 2 was defined,and acoustic surveys were purposefully extended to the selected fish assemblages(i.e.,endemic Coreius species) that was acquired by the size and species selectivity of the gillnet sampling.The relative proportion of fish species in acoustic surveys was allocated based on the composition(%) of the harvest in the gillnet surveys.Geostatistical simulations were likewise used to generate spatial patterns of fish distribution,and to determine the absolute abundance of the selected fish assemblages.We observed both the species composition and the spatial distribution of the selected fish assemblages changed significantly after implementation of new flow regulation in the TGR,wherein an immediate sharp population decline in the Coreius occurred.Our results strongly suggested that the new flow regulation in the TGR impoundment adversely affected downstream fish species,particularly the endemic Coreius species.To determine the factors responsible for the decline,we associated the variation in the fish assemblage patterns with changes in the environment and determined that substrate erosion resulting from trapping practices in the TGR likely played a key role. | TAO JiangPing GONG YuTian TAN XiChang YANG Zhi CHANG JianBo | 2012 | Science China(Life Sciences)2012，55，7： | 12 |
| 5 | Interface issues of lithium metal anode for high-energy batteries: Challenges, strategies, and perspectives显示文摘Lithium(Li)metal is considered as one of the most promising anode materials for next-generation high-energy-density storage systems.However,the practical application of Li metal anode is hindered by interfacial instability and air instability due to the highly reactivity of Li metal.Unstable interface in Li metal batteries(LMBs)directly dictates Li dendrite growth,“dead Li”and low Coulombic efficiency,resulting in inferior electrochemical performance of LMBs and even safety issues.In addition,its sensitivity to ambient air leads to the severe corrosion of Li metal anode,high requirements of production and storage,and increased manufacturing cost.Plenty of efforts in recent years have overcome many bottlenecks in these fields and hastened the practical applications of high-energy-density LMBs.In this review,we focus on emerging methods of these two aspects to fulfill a stable and low cost electrode.In this perspective,design artificial solid electrolyte interphase(SEI)layers,construct three-dimensional conductive current collectors,optimize electrolytes,employ solid-state electrolytes,and modify separators are summarized to be propitious to ameliorate interfacial stability.Meanwhile,ex situ/in situ formed protective layers are highlighted in favor of heightening air stability.Finally,several possible directions for the future research on advanced Li metal anode are addressed. | Yiyao Han Bo Liu Zhen Xiao Wenkui Zhang Xiuli Wang Guoxiang Pan Yang Xia Xinhui Xia Jiangping Tu | 2021 | InfoMat2021，3，2： | 11 |
| 6 | Species identification of Chinese sturgeon using acoustic descriptors and ascertaining their spatial distribution in the spawning ground of Gezhouba Dam显示文摘This study has developed an improved subjective approach of classification in conjunction with Stepwise DFA analysis to discriminate Chinese sturgeon signals from other targets. The results showed that all together 25 Chinese sturgeon echo-signals were detected in the spawning ground of Gezhouba Dam during the last 3 years, and the identification accuracy reached 90.9%. In Stepwise DFA, 24 out of 67 variables were applied in discrimination and identification. PCA combined with DFA was then used to ensure the significance of the 24 variables and detailed the identification pattern. The results indicated that we can discriminate Chinese sturgeon from other fish species and noise using certain descriptors such as the behaviour variables, echo characteristics and acoustic cross-section characteristics. However, identification of Chinese sturgeon from sediments is more difficult and needs a total of 24 variables. This is due to the limited knowledge about the acoustic-scattering properties of the substrate regions. Based on identified Chinese sturgeon individuals, 18 individuals were distributed in the region between the site of Gezhouba Dam and Miaozui reach, with a surface area of about 3.4 km2. Seven individuals were distributed in the region between Miaozui and Yanshouba reach, with a surface area of about 13 km2. | TAO JiangPing QIAO Ye TAN XiChang CHANG JianBo | 2009 | Chinese Science Bulletin2009，54，21： | 11 |
| 7 | Dynamical Solidification Behaviors and Metal Flow during Continuous Semisolid Extrusion Process of AZ31 Alloy显示文摘In this paper, a novel near-net-shape forming process, continuous semisolid extrusion process (CSEP) of AZ31 alloy was proposed, and the dynamical solidification behaviors and metal flow during the process were firstly investigated. During casting AZ31 alloy by this process, non-uniform microstructure distributions and non-equilibrium solidification region near the roll surface were found in the roll-shoe gap. Microstructural evolution from dendrite to rosette and spherical grains was observed during the casting by CSEP. Casting temperature, roll-shoe gap width and cooling ability have great effect on casting process and metal flow, so these factors should be carefully controlled, a proper casting temperature of 710-750℃ is suggested. The white α phases were strongly stretched during the processing, and the remnant liquids are correspondingly distributes along the solid phase boundaries and also show stripped lines. | Renguo Cuan Liqing Chen Jiangping Li Fuxing Wang | 2009 | Journal of Materials Science & Technology2009，25，3： | 10 |
| 8 | Vegetable Genetic Resources in China显示文摘China is recognized as an important region for plant biodiversity based on its vast and historical collection of vegetable germplasm. The aim of this review is to describe the exploration status of vegetable genetic resources in China, including their collection, preservation, evaluation, and utilization. China has established a number of national-level vegetable genetic resources preservation units, including the National Mid-term Genebank for Vegetable Germplasm Resources, the National Germplasm Repository for Vegetatively-Propagated Vegetables, and the National Germplasm Repository for Aquatic Vegetables. In 2015, at least 36 000 accessions were collected and preserved in these units. In the past decade, 44 descriptors and data standards for different species have been published, and most accessions have been evaluated for screening the germplasms for specific important traits such as morphological characteristics, disease resistance, pest resistance, and stress tolerance.Moreover, the genetic diversity and evolution of some vegetable germplasms have been evaluated at the molecular level. Recently, more than 1 000 accessions were distributed to researchers and breeders each year by various means for vegetable research and production. However,additional wild-relative and abroad germplasms from other regions need to be collected and preserved in the units to expand genetic diversity.Furthermore, there is a need to utilize advanced techniques to better understand the background and genetic diversity of a wide range of vegetable genetic resources. This review will provide agricultural scientists' insights into the genetic diversity in China and provide information on the distribution and potential utilization of these valuable genetic resources. | WANG Haiping LI Xixiang SONG Jiangping | 2018 | Horticultural Plant Journal2018，4，2： | 10 |
| 9 | Revisiting Scientific Issues for Industrial Applications of Lithium–Sulfur Batteries显示文摘Inspired by high theoretical energy density(-2600 W h kg^(-1))and cost-effectiveness of sulfur cathode,lithium–sulfur batteries are receiving great attention and considered as one of the most promising next-generation high-energy-density batteries.However,over the past decades,the energy density and reliable safety levels as well as the commercial progress of lithium-sulfur batteries are still far from satisfactory due to the disconnection and huge gap between fundamental research and practical application. | Bo Liu Ruyi Fang Dong Xie Wenkui Zhang Hui Huang Yang Xia Xiuli Wang Xinhui Xia Jiangping Tu | 2018 | Energy & Environmental Materials2018，1，4： | 9 |
| 10 | Function of note strings in Japanese Tit alarm calls to the Common Cuckoo:a playback experiment显示文摘Background: Birds produce alarm calls to convey information about threats. Some Passerine alarm calls consist of several note strings, but few studies have examined their function. Previous studies have shown that Japanese Tits(Parus minor) can alter the calling rate and number and combination of notes in response to predators. We previously found the combinations of note types in Japanese Tit alarm calls to be significantly different in response to the Sparrowhawk(Accipiter nisus) and Common Cuckoo(Cuculus canorus).Methods: Through playback experiments, we tested whether the note strings in Japanese Tit alarm calls to the Common Cuckoo have different functions in conveying information. The note strings of selected alarm calls were divided into the categories of C and D, and different calls were then constructed separately based on the two note string categories. Original alarm calls(C–D), C calls and D calls were played back to male Japanese Tits during the incubation period.Results: Male Japanese Tits had a significantly stronger response to C calls than to C–D calls, and they showed a significantly stronger response to both C and C–D calls than to D calls, suggesting that Japanese Tits discriminated between the C and D calls.Conclusions: Our study demonstrated that the C-and D-category note strings of Japanese Tit alarm calls to the Common Cuckoo have different functions, which supports the previous finding that different note strings in an alarm call can provide different information to receivers. However, the exact meanings of these note strings are not yet known, and further investigation is therefore required. | Jiangping Yu Weiwei Lv Hongwei Xu Nehafta Bibi Yangyang Yu Yunlei Jiang Wei Liang Haitao Wang | 2017 | Avian Research2017，8，3： | 8 |
| 11 | Surface pollen distribution patterns in Beibu Gulf and corresponding sediment dynamics environment显示文摘The Beibu Gulf is a semi-enclosed gulf in the northwest of the South China Sea.We palynologically analyzed 306 surface sediment samples from the eastern Beibu Gulf to improve bioclimatic interpretation of fossil pollen records there.Surface pollen assemblages could be classified into five pollen regions based on the distributions of total,arboreal,herbaceous and fern pollen concentrations.Four high-concentration and three low-concentration subregions could be distinguished within these regions.The distribution patterns of surface pollen assemblages were consistent with those of grain sizes of surface sediments.Sediments from regions with high pollen concentrations were very fine and fine silts (>7.0,<0.008 mm),whereas those with low pollen concentrations were fine sand (<3.5,>0.088 mm).Sedimentary heterogeneity of surface pollen assemblages was closely related to pollen source,transportation and sedimentation controlled by ocean currents,tides and waves,and oceanic bottom topography.Fern spores exhibited higher percentages along the east margins of the region,while arboreal types like Pinus increased in concentration towards the center.Herbaceous pollen appeared in high percentages around seacoasts near their source areas.Dacrydium and mangrove pollen were distributed near their source regions at low percentages.We discuss the sediment dynamic environments in the eastern Beibu Gulf based on surface pollen distributions.The estuary region is an important access to the sea basin and a depositional site for terrestrial pollen grains.Coastal regions can accumulate pollen due to the back-and-forth movements of tides there.Although ocean currents on a gulf scale tend to spread pollen grains,the interaction of multiple currents could lead to pollen accumulation and deposition.Low surface pollen concentrations in the northeast shallow-water regions of the eastern Beibu Gulf could be attributed to repeated washing and sediment floatation caused by severe wave activities during the summer.Strong tides in Qiongzhou Strait frequently wash the seabed and disadvantage pollen deposition,leading to low surface pollen concentrations there. | TONG GuoBan CHEN Lian LONG JiangPing LI TuanJie XIAO XiaYun TONG SongMei | 2012 | Chinese Science Bulletin2012，57，8： | 8 |
| 12 | Host metabolism dysregulation and cell tropism identification in human airway and alveolar organoids upon SARS-CoV-2 infection显示文摘The coronavirus disease 2019(COVID-19)pandemic is caused by infection with the severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),which is spread primary via respiratory droplets and infects the lungs.Currently widely used cell lines and animals are unable to accurately mimic human physiological conditions because of the abnormal status of cell lines(transformed or cancer cells)and species differences between animals and humans.Organoids are stem cell-derived selforganized three-dimensional culture in vitro and model the physiological conditions of natural organs.Here we showed that SARS-CoV-2 infected and extensively replicated in human embryonic stem cells(hESCs)-derived lung organoids,including airway and alveolar organoids which covered the complete infection and spread route for SARS-CoV-2 within lungs.The infected ceils were ciliated,club,and alveolar type 2(AT2)cells,which were sequentially located from the proximal to the distal airway and terminal alveoli,respectively.Additionally,RNA-seq revealed early cell response to virus infection including an unexpected downregulation of the metabolic processes,especially lipid metabolism,in addition to the well-known upregulation of immune response.Further,Remdesivir and a human neutralizing antibody potently inhibited SARS-CoV-2 replication in lung organoids.Therefore,human lung organoids can serve as a pathophysiological model to investigate the underlying mechanism of SARS-CoV-2 infection and to discover and test therapeutic drugs for COVID-19. | Rongjuan Pei Jianqi Feng Yecheng Zhang Hao Sun Lian Li Xuejie Yang Jiangping He Shuqi Xiao Jin Xiong Ying Lin Kun Wen Hongwei Zhou Jiekai Chen Zhili Rong Xinwen Chen | 2021 | Protein & Cell2021，12，9： | 7 |
| 13 | Single-cell analysis reveals bronchoalveolar epithelial dysfunction in COVID-19 patients显示文摘Dear Editor,In 2019,a zoonotic coronavirus named severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)was identified as the causative agent of Coronavirus Disease 2019(COVID-19).As of 8 June 2020,the World Health Organization(WHO)has reported 6,912,751 globally confirmed cases with 400,469 deaths.Although generally causes mild disease,SARS-CoV-2 infection can result in serious outcomes,including acute lung injury(ALI)and acute respiratory distress syndrome(ARDS),the leading cause of mortality in patients with comorbidities.Recent autopsy studies of COVID-19 patients revealed mononuclear infiltration and excessive production of mucus in the infected lung,especially in the damaged small airways and alveoli(Bian and Team,2020;Liu et al.,2020). | Jiangping He Shuijiang Cai Huijian Feng Baomei Cai Lihui Lin Yuanbang Mai Yinqiang Fan Airu Zhu Huang Huang Junjie Shi Dingxin Li' Yuanjie Wei Yueping Li Yingying Zhao’ Yuejun Pan He Liu Xiaoneng Mo Xi He Shangtao Cao FengYu Hu Jincun Zhao Jie Wang Nanshan Zhong Xinwen Chen Xilong Deng Jiekai Chen | 2020 | Protein & Cell2020，11，9： | 7 |
| 14 | Sheep manure application increases soil exchangeable base cations in a semi-arid steppe of Inner Mongolia显示文摘The long-term productivity of a soil is greatly influenced by cation exchange capacity(CEC).Moreover,interactions between dominant base cations and other nutrients are important for the health and stability of grassland ecosystems.Soil exchangeable base cations and cation ratios were examined in a 11-year experiment with sheep manure application rates 0–1,500 g/(m2?a) in a semi-arid steppe in Inner Mongolia of China,aiming to clarify the relationships of base cations with soil p H,buffer capacity and fertility.Results showed that CEC and contents of exchangeable calcium(Ca2+),magnesium(Mg2+),potassium(K+) and sodium(Na+) were significantly increased,and Ca2+ saturation tended to decrease,while K+ saturation tended to increase with the increases of sheep manure application rates.The Ca2+/Mg2+ and Ca2+/K+ ratios decreased,while Mg2+,K+ and Na+ saturations increased with increasing manure application rates.Both base cations and CEC were significantly and positively correlated with soil organic carbon(SOC) and soil p H.The increases of SOC and soil p H would be the dominant factors that contribute to the increase of cations in soil.On a comparison with the initial soil p H before the experiment,we deduced that sheep manure application could partly buffer soil p H decrease potentially induced by atmospheric deposition of nitrogen and sulfur.Our results indicate that sheep manure application is beneficial to the maintenance of base cations and the buffering of soil acidification,and therefore can improve soil fertility in the semi-arid steppes of northeastern China. | YuGe ZHANG Shan YANG MingMing FU JiangPing CAI YongYong ZHANG RuZhen WANG ZhuWen XU YongFei BAI Yong JIANG | 2015 | Journal of Arid Land2015，7，3： | 7 |
| 15 | Vertical Distribution of Soil Carbon, Nitrogen, and Phosphorus in Typical Chinese Terrestrial Ecosystems显示文摘Characterization of the vertical distribution of soil organic carbon(C), nitrogen(N), and phosphorus(P) may improve our ability to accurately estimate soil C, N, and P storage. Based on a database of 21 354 records in 74 long-term monitoring plots from 2004 to 2013 in the Chinese Ecosystem Research Network(CERN), we built fitting functions to quantify the vertical distribution of soil C, N, and P(up to 100 cm depth) in the typical Chinese terrestrial ecosystems. The decrease of soil C, N, and P content with depth can be well fitted with various mathematical functions. The fitting functions differed greatly between artificial(agriculture) and natural(desert, forest, and grassland) ecosystems, and also differed with respect to soil C, N, and P content. In both the artificial and natural ecosystems, the best fitting functions were exponential functions for C, quadratic functions for N, and quadratic functions for P. Furthermore, the stoichiometric ratios of soil C, N, and P were ranked in descending order: grassland > forest > agriculture > desert, and were also associated with climate. This study is the first to build the fitting functions for the profile distribution of soil C, N, and P in China at a national scale. Our findings provide a scientific basis to accurately assess the storage of C, N, and P in soils at a large scale, especially for the integrative analysis of historical data. | CHAI Hua YU Guirui HE Nianpeng WEN Ding LI Jie FANG Jiangping | 2015 | Chinese Geographical Science2015，25，5： | 7 |

| 19 | Analysis of factors affecting the prognosis of transcatheter arterial chemoembolization for hepatitis B-related hepatocellular carcinoma显示文摘Objectives:The purpose of this study was to investigate the prognostic factors for transcatheter arterial chemoembolization(TACE)for hepatitis B-related hepatocellular carcinoma(HCC).Materials and methods:The variables that may affect overall survival(OS),such as age,gender,AFP,Child Pugh classification,body mass index,HBV-DNA,Hbe Ag,tumor number,tumor diameter,BCLC stage,embolization method,ablation therapy,and targeted therapy,were analyzed by single factor and many factor COX regression.In addition,predictive factors of OS were stratified and a Kaplan-Meier survival curve was drawn.Results:Among the 136 patients,the median follow-up time was 14.5 months(range:2–72 months).HCC patients with the tumor diameter<3 cm had the highest survival rate,followed by patients with a tumor diameter of 3–5 cm;the survival rate of patients with the tumor diameter(greater than 5 cm)was the lowest.Among the BCLC stages,stage A patients had the highest survival rate,followed by stage B and stage C patients,which had the lowest survival rate.The survival rate of Child Pugh grade A patients was higher than those with Child Pugh grade B.Compared with patients who did not undergo ablation treatment,the survival rate of patients with combined ablation treatment was relatively high.The survival rate of patients receiving drug-eluting beads transarterial chemoembolization(DEB-TACE)treatment was higher than those receiving conventional transarterial chemoembolization(c TACE)treatment.Additionally,repeated TACE treatment improved the OS rate of patients.These six factors were related to patient prognosis and the differences were statistically significant(P<0.05).Conclusions:Tumor diameter,BCLC stage,TACE repetition,and TACE combined with ablation were independent prognostic factors of OS. | Jiangping Cun Yonghui Xu Weidong Li Xingxiang Zhao | 2021 | Journal of Interventional Medicine2021，4，2： | 7 |
| 20 | Controller Parameter Tuning of Delta Robot Based on Servo Identification显示文摘High-speed pick-and-place parallel robot is a system where the inertia imposed on the motor shafts is real-time changing with the system configurations.High quality of computer control with proper controller parameters is conducive to overcoming this problem and has a significant effect on reducing the robot's tracking error.By taking Delta robot as an example,a method for parameter tuning of the fixed gain motion controller is presented.Having identifying the parameters of the servo system in the frequency domain by the sinusoidal excitation,the PD+feedforward control strategy is proposed to adapt to the varying inertia loads,allowing the controller parameters to be tuned by minimizing the mean square tracking error along a typical trajectory.A set of optimum parameters is obtained through computer simulations and the effectiveness of the proposed approach is validated by experiments on a real prototype machine.Let the traveling plate undergoes a specific trajectory and the results show that the tracking error can be reduced by at least 50%in comparison with the conventional auto-tuning and Z-N methods.The proposed approach is a whole workspace optimization and can be applied to the parameter tuning of fixed gain motion controllers. | ZHAO Qing WANG Panfeng MEI Jiangping | 2015 | Chinese Journal of Mechanical Engineering2015，28，2： | 6 |
