| 1 | Distributed Adaptive Fault-Tolerant Output Regulation of Heterogeneous Multi-Agent Systems With Coupling Uncertainties and Actuator Faults显示文摘In this paper, we consider the distributed adaptive fault-tolerant output regulation problem for heterogeneous multiagent systems with matched system uncertainties and mismatched coupling uncertainties among subsystems under the influence of actuator faults. First, distributed finite-time observers are proposed for all subsystems to observe the state of the exosystem. Then, a novel fault-tolerant controller is designed to compensate for the influence of matched system uncertainties and actuator faults. By using the linear matrix inequality technique, a sufficient condition is provided to guarantee the solvability of the considered problem in the presence of mismatched coupling uncertainties. Moreover, it is shown that the system in closed-loop with the developed controller can achieve output regulation by using the Lyapunov stability theory and cyclic-small-gain theory.Finally, a numerical example is given to illustrate the effectiveness of the obtained result. | Chao Deng Weinan Gao Weiwei Che | 2020 | IEEE/CAA Journal of Automatica Sinica2020，7，4： | 6 |
| 2 | Self-transforming ultrathin α-Co(OH)2 nanosheet arrays from metal-organic framework modified graphene oxide with sandwichlike structure for efficient electrocatalytic oxygen evolution显示文摘Developing efficient and low-cost electrocatalysts for oxygen evolution reaction(OER)with high electrochemical activity and durability for diverse renewable and sustainable energy technologies remains challenging.Herein,an ultrasonic-assisted and coordination modulation strategy is developed to construct sandwich-like metal-organic framework(MOF)derived hydroxide nanosheet(NS)arrays/graphene oxide(GO)composite via one-step self-transformation route.Inducing from unsteady state,the dodecahedral ZIF-67 with Co^2+in tetrahedral coordination auto-converts into defect-rich ultrathin layered hydroxides with the interlayered ion NO3-.The self-transforming a-Co(OH)2/GO nanosheet arrays from ZIF-67(Co(OH)2-GNS)change the coordination mode of Co^2+and bring about the exposure of more metal active sites,thereby enhancing the spatial utilization ratio within the framework.As monometal-based electrocatalyst,the optimized Co(OH)2-GNS exhibits remarkable OER catalytic performance evidenced by a low overpotential of 259 mV to achieve a current density of 10 mA·cm-2 in alkaline medium,even exceeding commercial RuO2.During the oxygen evolution process,electron migration can be accelerated by the interfacial/in-plane charge polarization and local electric field,corroborated by the off-axis electron holography.Density functional theory(DFT)calculations further studied the collaboration between ultrathin Co(OH)2 NS and GO,which leads to lower energy barriers of intermediate products and greatly promotes electrocatalytic property. | Mengqiu Huang Weiwei Liu Lei Wang Jiwei Liu Guanyu Chen Wenbin You Jie Zhang Lijun Yuan Xuefeng Zhang Renchao Che | 2020 | Nano Research2020，13，3： | 4 |

| 4 | Observer-based H-infinity control in multiple channel networked control systems with random packet dropouts显示文摘This paper investigates the observer-based H-infinity control problem for networked control systems (NCSs) with random packet dropouts.A general packet dropout model with multiple independent stochastic variables in the multiple channels case is adopted to describe the data missing in the limited communication channels.With the consideration of the sensor-to-controller and controller-to-actuator packet dropouts at the same time,a new method is proposed based on a separation lemma to design an observer-based H-infinity controller,which exponentially stabilizes the closed-loop system in the sense of mean square and also achieves a prescribed H-infinity disturbance attenuation level.A numerical example is given to illustrate the effectiveness of the proposed control method. | Weiwei CHE Jianliang WANG Guanghong YANG | 2010 | 控制理论与应用(英文版)2010，8，3： | 1 |
| 5 | Non-fragile state feedback H-infinity control for discrete-time systems with quantized signals显示文摘This paper presents a study on the problem of non-fragile state feedback H-infinity controller design for linear discrete-time systems with quantized signals. The quantizers considered here are dynamic and time-varying. With the consideration of controller gain variations and quantized signals at the same time, a new non-fragile H-infinity control strategy is proposed with updating quantizer's parameters, such that the quantized closed-loop system is asymptotically stable and with a prescribed H-infinity performance bound. An example is presented to illustrate the effectiveness of the proposed control strategy. | Weiwei CHE Guanghong YANG | 2009 | 控制理论与应用(英文版)2009，7，1： | 1 |

| 7 | Architecture Design Research Based on the Concept of Ecological显示文摘With the continuous development of industry and the progress of science and technology, energy resources consumption becomes increasingly serious. Under the sustainable development of environment, energy saving, environmental protection requirements improve continuously. As an energy-intensive industry occupying one third of the total energy consumption, the construction industry’s energy consumption problem becomes increasingly serious. In order to promote human ecological balance and sustainable development of society, combining the ecological concept into the architectural design is imminent. The so-called ecological architecture is based on the nature, guided by sustainable development, and combines the ecological theory into the architecture. This paper briefl y introduces the ecological architecture, discusses the application of ecological ideas in architectural design and its design principle, which plays an important role in the ecological construction’s integrating in architectural design. | Li Che Zhang Weiwei Chen Kui Hao Yong Tang Kang | 2016 | International Journal of Technology Management2016，，5： | 0 |
| 8 | Signal difference-based deadband H_∞ control approach for networked control systems with limited resources显示文摘This paper investigates a signal difference-based deadband H∞ control approach for networked control systems(NCSs)with limited resources. The effects of variable network-induced delays, sampling intervals and data transmitting deadbands are considered simultaneously and the model of the NCS is presented.A Lyapunov functional is adopted, which makes full use of the network characteristic information including the bounds of network delay(BND), the bounds of sampling interval(BSI) and the bounds of transmission deadband(BTD). In the meanwhile, the new H∞ performance analysis and controller design conditions for the NCSs are proposed, which describe the relationship of BND,BSI, BTD and the system's performance. Three examples are used to illustrate the advantages of the proposed methods. The results have shown that the proposed method not only effectively reduces the data traffic, but also guarantees the system asymptotically stable and achieves the prescribed H∞ disturbance attenuation level. | Yingying Liu Weiwei Che Yunkai Chu | 2015 | Journal of Systems Engineering and Electronics2015，26，3： | 0 |
