| 1 | Robust current control design of a three phase voltage source converter显示文摘In this paper,a robust design method for current control is proposed to improve the performance of a three phase voltage source converter(VSC)with an inductorcapacitor-inductor(LCL)filter.The presence of the LCL filter complicates the dynamics of the control system and limits the achievable control bandwidth(and the overall performance),particularly when the uncertainty of the parameters is considered.To solve this problem,the advanced H?control theory is employed to design a robust current controller in stationary coordinates.Both control of the fundamental frequency current and suppression of the potential LC resonance are considered.The design procedure and the selection of the weight functions are presented in detail.A conventional proportional-resonant PR controller is also designed for comparison.Analysis showed that the proposed H∞ current controller achieved a good frequency response with explicit robustness.The conclusion was verified on a 5 kW VSC that had a LCL filter. | Wenming GONG Shuju HU Martin SHAN Honghua XU | 2014 | Journal of Modern Power Systems and Clean Energy2014，2，1： | 13 |
| 2 | Genome Warehouse: A Public Repository Housing Genome-scale Data显示文摘The Genome Warehouse(GWH)is a public repository housing genome assembly data for a wide range of species and delivering a series of web services for genome data submission,storage,release,and sharing.As one of the core resources in the National Genomics Data Center(NGDC),part of the China National Center for Bioinformation(CNCB;http://gffzz77e3413bc06540eds6fn9pn5kookk6cx9.ffgz.tsg.suse.edu.cn),GWH accepts both full and partial(chloroplast,mitochondrion,and plasmid)genome sequences with different assembly levels,as well as an update of existing genome assemblies.For each assembly,GWH collects detailed genome-related metadata of biological project,biological sample,and genome assembly,in addition to genome sequence and annotation.To archive high-quality genome sequences and annotations,GWH is equipped with a uniform and standardized procedure for quality control.Besides basic browse and search functionalities,all released genome sequences and annotations can be visualized with JBrowse.By May 21,2021,GWH has received 19,124 direct submissions covering a diversity of 1108 species and has released 8772 of them.Collectively,GWH serves as an important resource for genomescale data management and provides free and publicly accessible data to support research activities throughout the world.GWH is publicly accessible at http://gffzz77e3413bc06540eds6fn9pn5kookk6cx9.ffgz.tsg.suse.edu.cn/gwh. | Meili Chen Yingke Ma Song Wu Xinchang Zheng Hongen Kang Jian Sang Xingjian Xu Lili Hao Zhaohua Li Zheng Gong Jingfa Xiao Zhang Zhang Wenming Zhao Yiming Bao | 2021 | Genomics, Proteomics & Bioinformatics2021，19，4： | 12 |
| 3 | Design and Experiment of Electronic-hydraulic Loading Test-bed Based on Tractor's Hydraulic Steering By-wire显示文摘An Electro-hydraulic loading system is designed based on a test-bed of tractor's hydraulic steering by-wire. To simulate the steering resistance driving tractor in many kinds of soils and roads,the loading force is controlled to make proportional and continuous variable by an electro-hydraulic proportional relief valve. A steering resistance loading test-bed is built to test three kinds of steering resistance including constant,step and sine style. Tire lateral resistance is also tested under different steering conditions. The result shows that the electro-hydraulic loading system has high stability and following performance. Besides,the system's steady state error is lower than 3. 1%,and it meets the test requirement of tractor's hydraulic steering by-wire. | Yue JIN Yang LU Jiahui GONG Zhixiong LU Wenming LI Jungan WU | 2015 | Asian Agricultural Research2015，7，12： | 1 |
| 4 | Ultra-long room temperature phosphorescence of indium-based organic inorganic metal halides for naked-eye-visible afterglow显示文摘Solid-state molecules based on room-temperature phosphorescent(RTP)emission have received extensive attention due to their special optical properties of triplet excitons.However,there are still few solid molecular systems with naked-eye-visible afterglow characteristics.Herein,we introduce 4-phenylbenzylamine(namely PBA)with a long conjugated system into common non-toxic In^(3+)to form an indium-based organic inorganic halide,whose chemical formula is PBA_(3)[InCl_6]·H_(2)O.Interestingly,this hybrid halide generates a RTP emission at 617 nm with a lifetime decay as long as 290.4 ms,expressing a naked-eye-visible afterglow for more than 7 s.The mechanism study shows that the long lifetime RTP originated from the specific lamellar stacking of organic molecules and metal halide units,facilitating the interaction between the inorganic layers and organic layers.Therefore,the material can be potentially used in emergency lighting,information security,and other fields.Meanwhile,this work provides a reference for the design and implementation of a more efficient organic-inorganic hybrid system with the ultralong RTP emission. | Heng Yu Hao Gong Zhaorui Hua Yang Zhang Wenming Sun Shuyan Gong Ganglong Cui Yang Tian Hongbing Fu | 2023 | Science China Chemistry2023，66，9： | 0 |
