| 1 | Event-triggered encirclement control of multi-agent systems with bearing rigidity显示文摘In recent years, the problem of multi-agent encirclement has attained much attention and was extensively studied. However, few work consider the factor that the on-board calculation as well as the communication capacity in the multi-agent system is limited. We investigate the encirclement control by employing the newly developed bearing rigidity theory and event-triggered mechanism. Firstly, in order to reduce the onboard loads,the event-triggered mechanism is considered in the framework and further an event-triggered control law based on bearing rigidity is proposed. The input-to-state stability(ISS) of networked agents is also analyzed by using the Lyapunov method and the cyclic-small-gain theory. In addition, the lower bound for the inter-event times is provided. Finally, to verify the efficiency and feasibility of the proposed encirclement control law, numerical experiments are investigated. | Yangguang YU Zhiwen ZENG Zhongkui LI Xiangke WANG Lincheng SHEN | 2017 | Science China(Information Sciences)2017，60，11： | 6 |
| 2 | Overview and Development of Variable Frequency AC Generators for More Electric Aircraft Generation System显示文摘With the development of more electric aircraft(MEA),higher demands for electrical energy are put forward in generation systems.Compared to constant frequency AC(CFAC)generation systems,the constant speed drive(CSD)is eliminated and integrated starter/generator(SG)can be realized in variable frequency AC(VFAC)generation systems.In this paper,an overview of VFAC generators for safety-critical aircraft applications is presented,with a particular focus on the key features and requirements of candidate generators and the starting control strategies.Wound rotor synchronous machines(WRSMs)are typical generators used in VFAC generation systems so far.Meanwhile,hybrid excitation synchronous machines(HESMs)and cage-type induction machines are promising candidates for VFAC generation systems.The generation operation of WRSM is relatively mature,however,the SG technology of WRSM is still full of challenges.As one of the most important issues,the starting excitation methods of WRSM are summarized.An HESM-based VFAC SG system is proposed and developed in this paper.The experimental results show that the starting mode,transition mode and generating mode of the VFAC SG system are realized.The continuous progress of VFAC generation system makes great contributions to the realization of MEA. | Zhuoran Zhang Jincai Li Ye Liu Yanwu Xu Yangguang Yan | 2017 | Chinese Journal of Electrical Engineering2017，3，2： | 4 |

| 7 | Sulfur vs. tellurium: the heteroatom effects on the nonfullerene acceptors显示文摘The effect of chalcogen heteroatom variation on donor materials has been systematically investigated. However, this effect on acceptors has rarely been explored. Herein, nonfullerene acceptors BFPSP and BFPTP were reported by simply changing the chalcogen atoms from S to Te. The differences between BFPSP and BFPTP in light absorption, energy levels, excited-state lifetimes, energy loss, charge mobilities, morphology, and photovoltaic properties were systematically investigated to understand the heteroatom effects. More importantly, the electroluminescence spectra, external quantum efficiency of photovoltaics and TDDFTcalculations revealed that the triplet excited state(T1) in energy of BFPTP equals to the charge transfer(CT) state in PBDBT:BFPTP, which allows T1 excitons, generated by intersystem crossing, to split into free charges to contribute to the efficiency.This contribution provides a strategy for tuning the photophysical properties of nonfullerene acceptors and designing high performance triplet materials for OSCs. | Lei Yang Linqing Qin Yunxiao Xu Huotian Zhang Lei Lv Kepeng Chen Xinyu Sui Yangguang Zhong Yuan Guo Feng Gao Jianzhang Zhao Yuhao Li Xinfeng Liu Yuanping Yi Xinhui Lu Aidong Peng Hui Huang | 2019 | Science China Chemistry2019，62，7： | 1 |
| 8 | Visible-light photocatalytic H_2 evolution over a series of transition metal substituted Keggin-structure heteropoly blues显示文摘The visible light photocatalytic H 2 evolution activities of a series of transition-metal substituted Keggin-structure heteropoly blues K 6 SiW 11 O 39 M(H 2 O)·nH 2 O (M=Co,Ni,Cu and Zn) were systematically studied with Pt nanoparticles as co-catalyst.The H 2 evolution rates were 150,98,65 and 48 mol h-1g-1 for SiW 11 Cu,SiW 11 Ni,SiW 11 Co and SiW 11 Zn,respectively,meaning that the order of photocatalytic activity of these heteropoly blues from transition-metal substituted polyoxometalates was:SiW 11 Cu > SiW 11 Ni > SiW 11 Co > SiW 11 Zn.The catalysts could be efficiently reused for at least 5 cycles. | ZhenLi Wang Ying Lu YangGuang Li ShiMing Wang EnBo Wang | 2012 | Chinese Science Bulletin2012，57，18： | 1 |

| 19 | Comparative Assessment on Microstructure and Properties of in-situ TiC+Ti_(5)Si_(3)Reinforced TiAl-Sn-Zr Matrix Composites by Spark Plasma Sintering and Argon Protected Sintering显示文摘The effects of SiC particles(SiCp)on high temperature oxidation behavior of titanium matrix composites(TMCs)under different powder metallurgy processes were investigated.In situ Ti C+Ti_(5)Si_(3)reinforced titanium matrix composites were prepared by discharge plasma sintering(SPS)and argon protective sintering(APS).The results show that the two processes have a negligible effect on the composition and hardness of the samples,but the hardness of the two samples is significantly improved by adding SiCp.The apparent porosity of SPS process is obviously smaller than that of APS process,whereas,the apparent porosity increases slightly with the addition of SiCp.The oxide layer thickness and mass gain of the samples obtained by SPS process are smaller than those obtained by APS process.The oxide thickness and mass gain of both processes are further reduced by adding SiCp.The SPS composites showed the best high temperature oxidation resistance.Therefore,TMCs with Si Cp by SPS can effectively improve the high-temperature oxidation behavior of the materials. | 姚辉 许晓静 CAI Chengbin LI Chen CHEN Fenghua LIU Yangguang XIAO Yishui | 2023 | Journal of Wuhan University of Technology(Materials Science)2023，38，1： | 0 |
| 20 | Accelerating solar driven CO_(2) reduction via sulfur-doping boosted water dissociation and proton transfer显示文摘Exploring efficient photocatalysts for solar driven CO_(2) reduction with water(H_(2)O)as a proton donor is highly imperative but remains a great challenge because the synchronous enhancement of CO_(2) activation,H_(2)O dissociation and proton transfer is hardly achieved on a photocatalyst.Particularly,the sluggish H_(2)O dissociation impedes the photocatalytic CO_(2) reduction reaction involving multiple proton–electron coupling transfer processes.Herein,a sulfur-doped BiOCl(S-BiOCl)photocatalyst with abundant oxygen vacancies(OV)is developed,which exhibits broadband-light harvesting across solar spectrum and distinct photothermal effect due to photochromism.For photocatalytic CO_(2) reduction with H_(2)O in a gas–solid system,the high CO yield of 49.76μmol·g_(cat)^(-1)·h^(-1) with 100%selectivity is achieved over the S-BiOCl catalyst under a simulated sunlight.The H_(2)O-assisted CO_(2) reduction reaction on S-BiOCl catalyst is triggered by photocatalysis and the photothermal heating further enhances the reaction rate.The kinetic isotope experiments indicate that the sluggish H_(2)O dissociation affects the whole photocatalytic CO_(2) reduction process.The presence of oxygen vacancies promotes the adsorption and activation of H_(2)O and CO_(2),and the doped S sites play a crucial role in boosting H_(2)O dissociation and accelerating the dynamic migration of hydrogen species.As a result,the ingenious integration of OV defects,S sites and photothermal effect in S-BiOCl catalyst conjointly contributes to the significant improvement in photocatalytic CO_(2) reduction performance. | Ke Yan Liang Chen Yangguang Hu Ting Wang Cong Chen Chao Gao Youju Huang Benxia Li | 2024 | Nano Research2024，17，3： | 0 |
