| 1 | Height and attitude active disturbance rejection controller design of a small-scale helicopter显示文摘Small-scale helicopters are very attractive because of their unique features.However,autonomous flight control for small-scale helicopters is still a challenging work because they are naturally unstable,strongly nonlinear,and sensitive to disturbances.In this paper,we focus on the design of a height and attitude active disturbance rejection controller(ADRC)for a small-scale helicopter constructed in our lab.Firstly,a comprehensive nonlinear model for the platform is presented,which is obtained through first principles modeling and system identification.The controller is designed using backstepping technique incorporated with extended state observer(ESO),which is used to estimate the unknown disturbances.Then,the estimate is introduced into the control law to compensate for the disturbances.The design specifications of military rotorcraft are introduced to guide the controller design to achieve specified control performance.Considering the physical limitations,reference models are designed to shape the desired control responses.At last,several flight simulations are carried out to validate the effectiveness and robustness of the proposed controller.The results show that the proposed controller works well and Level 1 performance can be achieved. | TANG Shuai YANG QiuHui QIAN ShaoKe ZHENG ZhiQiang | 2015 | Science China(Information Sciences)2015,58,3: | 8 |
| 2 | Exome sequencing reveals genetic architecture in patients with isolated or syndromic short stature显示文摘Short stature is among the most common endocrinological disease phenotypes of childhood and may occur as an isolated finding or in conjunction with other clinical manifestations.Although the diagnostic utility of clinical genetic testing in short stature has been implicated,the genetic architecture and the utility of genomic studies such as exome sequencing(ES)in a sizable cohort of patients with short stature have not been investigated systematically.In this study,we recruited 561 individuals with short stature from two centers in China during a 4-year period.We performed ES for all patients and available parents.All patients were retrospectively divided into two groups:an isolated short stature group(group I,n=257)and an apparently syndromic short stature group(group II,n=304).Causal variants were identified in 135 of 561(24.1%)patients.In group I,29 of 257(11.3%)of the patients were solved by variants in 24 genes.In group II,106 of 304(34.9%)patients were solved by variants in 57 genes.Genes involved in fundamental cellularprocess played an important role in the genetic architecture of syndromic short stature.Distinct genetic architectures and pathophysiological processes underlie isolated and syndromic short stature. | Xin Fan Sen Zhao Chenxi Yu Di Wu Zihui Yan Lijun Fan Yanning Song Yi Wang Chuan Li Yue Ming Baoheng Gui Yuchen Niu Xiaoxin Li Xinzhuang Yang Shiyu Luo Qiang Zhang Xiuli Zhao Hui Pan Mei Li Weibo Xia Guixing Qiu Pengfei Liu Shuyang Zhang Jianguo Zhang Zhihong Wu James R.Lupski Jennifer E.Posey Shaoke Chen Chunxiu Gong Nan Wu | 2021 | Journal of Genetics and Genomics2021,48,5: | 2 |

| 5 | High Output Performance and Ultra-Durable DC Output for Triboelectric Nanogenerator Inspired by Primary Cell显示文摘Triboelectric nanogenerator(TENG)is regarded as an effective strategy to convert environment mechanical energy into electricity to meet the distributed energy demand of large number of sensors in the Internet of Things(IoTs).Although TENG based on the coupling of triboelectrification and air-breakdown achieves a large direct current(DC)output,material abrasion is a bottleneck for its applications.Here,inspired by primary cell and its DC signal output characteristics,we propose a novel primary cell structure TENG(PC-TENG)based on contact electrification and electrostatic induction,which has multiple working modes,including contact separation mode,freestanding mode and rotation mode.The PC-TENG produces DC output and operates at low surface contact force.It has an ideal effective charge density(1.02 m Cm^(-2)).Meanwhile,the PC-TENG shows a superior durability with 99% initial output after 100,000 operating cycles.Due to its excellent output performance and durability,a variety of commercial electronic devices are powered by PC-TENG via harvesting wind energy.This work offers a facile and ideal scheme for enhancing the electrical output performance of DC-TENG at low surface contact force and shows a great potential for the energy harvesting applications in IoTs. | Shaoke Fu Wencong He Huiyuan Wu Chuncai Shan Yan Du Gui Li Ping Wang Hengyu Guo Jie Chen Chenguo Hu | 2022 | Nano-Micro Letters2022,14,9: | 1 |

| 7 | Second-order sliding mode attitude controller design of a small-scale helicopter显示文摘In this paper, the attitude control of a small-scale helicopter is investigated. The main rotor flapping dynamics is explicitly explored to improve the control performance. A two-layer control architecture is adopted:the inner loop controller is designed combining second-order sliding mode control with extended state observer to control the angular rates and yield good robustness properties with respect to model uncertainties; the outer loop controller is used to control the attitude. Experimental results show that the proposed controller yields excellent performance and robustness. | Shuai TANG Li ZHANG Shaoke QIAN Zhiqiang ZHENG | 2016 | Science China(Information Sciences)2016,59,11: | 1 |

| 13 | A conductive supramolecular hydrogel creates ideal endogenous niches to promote spinal cord injury repair显示文摘The current effective method for treatment of spinal cord injury(SCI)is to reconstruct the biological microenvironment by filling the injured cavity area and increasing neuronal differentiation of neural stem cells(NSCs)to repair SCI.However,the method is characterized by several challenges including irregular wounds,and mechanical and electrical mismatch of the material-tissue interface.In the current study,a unique and facile agarose/gelatin/polypyrrole(Aga/Gel/PPy,AGP3)hydrogel with similar conductivity and modulus as the spinal cord was developed by altering the concentration of Aga and PPy.The gelation occurred through non-covalent interactions,and the physically crosslinked features made the AGP3 hydrogels injectable.In vitro cultures showed that AGP3 hydrogel exhibited excellent biocompatibility,and promoted differentiation of NSCs toward neurons whereas it inhibited over-proliferation of astrocytes.The in vivo implanted AGP3 hydrogel completely covered the tissue defects and reduced injured cavity areas.In vivo studies further showed that the AGP3 hydrogel provided a biocompatible microenvironment for promoting endogenous neurogenesis rather than glial fibrosis formation,resulting in significant functional recovery.RNA sequencing analysis further indicated that AGP3 hydrogel significantly modulated expression of neurogenesis-related genes through intracellular Ca2+signaling cascades.Overall,this supramolecular strategy produces AGP3 hydrogel that can be used as favorable biomaterials for SCI repair by filling the cavity and imitating the physiological properties of the spinal cord. | Biao Yang Chengzhen Liang Di Chen Feng Cheng Yuang Zhang Shaoke Wang Jiawei Shu Xianpeng Huang Jingkai Wang Kaishun Xia Liwei Ying Kesi Shi Chenggui Wang Xuhua Wang Fangcai Li Qian Zhao Qixin Chen | 2022 | Bioactive Materials2022,7,9: | 0 |

| 15 | Assessing Dual Rh/Ru Cascade Catalysts in One-Pot Homogeneous Synthesis of Ethanol from Syngas and Methanol显示文摘The direct conversion of cheap syngas into value-added ethanol at an industrial scale is in high demand.Herein we disclose a one-pot homogeneous homologation of methanol to ethanol with syngas via a rhodium/ruthenium bimetallic catalytic approach.By introducing a catalytic amount of methyl iodide,methanol can be converted to ethanol with high selectivity(>91%ethanol).A syngas ratio of H_(2)/CO=4:1 was found to be optimal.Among various phosphine ligands tested,Rh-dppp catalyst gave the highest aldehyde pathway selectivity,thus providing an effective route for the synthesis of ethanol upon coupling with a Ru hydrogenation catalyst.The bite angle of the bisphosphine ligands dramatically influences the selectivity of the dual Rh/Ru metallic cascade catalysts.In line with the experimental findings,theoretical calculations predicted a rational trend of the selectivity of different bisphosphine ligands via varying bite angle properties. | Ji-Shu Zhang Ya-Fei Jiang Fanfu Guan Shaoke Zhang Cong-Qiao Xu Shao-Tao Bai Jialin Wen Jun Li Xumu Zhang | 2023 | CCS Chemistry2023,5,7: | 0 |
| 16 | Ultrahigh Performance Triboelectric Nanogenerator Enabled by Charge Transmission in Interfacial Lubrication and Potential Decentralization Design显示文摘Triboelectric nanogenerator (TENG) is a promising strategy for harvesting low frequency mechanical energy. However, the bottlenecks of limited electric output by air/dielectric breakdown and poor durability by material abrasion seriously restrict its further improvement. Herein, we propose a liquid lubrication promoted sliding mode TENG to address both issues. Liquid lubrication greatly reduces interface material abrasion, and its high breakdown strength and charge transmission effect further enhance device charge density. Besides, the potential decentralization design by the voltage balance bar effectively suppresses the dielectric breakdown. In this way, the average power density up to 87.26 W·m^(-2)·Hz^(-1), energy conversion efficiency of 48%, and retention output of 90% after 500,000 operation cycles are achieved, which is the highest average power density and durability currently. Finally, a cell phone is charged to turn on by a palm-sized TENG device at 2 Hz within 25 s. This work has a significance for the commercialization of TENG-based self-powered systems. | Wencong He Wenlin Liu Shaoke Fu Huiyuan Wu Chuncai Shan Zhao Wang Yi Xi Xue Wang Hengyu Guo Hong Liu Chenguo Hu | 2022 | Research2022,,4: | 0 |
| 17 | Chain-flip plate triboelectric nanogenerator arranged longitudinally under water for harvesting water wave energy显示文摘Triboelectric nanogenerator(TENG)is a new cost-effective blue energy harvesting technology for its great performance in low frequency.However,many related energy harvesters operate on water surface,ignoring the ocean’s depth.Herein,a chainflipped plate TENG(CFP-TENG),consisting of longitudinally arranged repeating units,is proposed to collect wave energy.The chain structure design allows the surface wave energy to act effectively on the underwater generator.The maximum output power per unit ocean area reaches 1.5 W·m^(-2) at a loading resistance of 30 MΩ.Optimization of device parameters and application demonstrations are explored.Compared with previous works,the utilization rate of wave energy has been significantly improved.This work not only provides a new method to optimize the output of TENG but also makes a crucial step in promoting practical applications of TENG in renewable blue energy. | Yan Du Qian Tang Shaoke Fu Chuncai Shan Qixuan Zeng Hengyu Guo Chenguo Hu | 2023 | Nano Research2023,16,9: | 0 |
