| 1 | EXPONENTIAL STABILITY OF LINEAR DISTRIBUTED PARAMETER SWITCHED SYSTEMS WITH TIME-DELAY显示文摘In this paper, the exponential stability analysis for ODE switched systems with time delay is extended to distributed parameter switched systems(DPSS) in Hilbert space. For a given family of exponential stable subsystems, this paper focuses on finding conditions to guarantee the overall DPSS' exponential stability. Based on semigroup theory, by applying piecewise Lyapunov-Krasovskii functionals method incorporated average dwell time approach, sufficient conditions for exponential stability are derived. These conditions are given in the form of linear operator inequalities(LOIs)where the decision variables are operators in Hilbert space, and the stability properties depend on switching rule. Being applied to heat switched propagation equations, these LOIs are reduced to standard Linear Matrix Inequalities(LMIs). Finally, a numerical example is given to illustrate the effectiveness of the proposed result. | BAO Leping FEI Shumin YU Lei | 2014 | Journal of Systems Science & Complexity2014，27，2： | 9 |
| 2 | Adaptive dynamic surface control for air-breathing hypersonic vehicle显示文摘This paper describes an adaptive control approach for an air-breathing hypersonic vehicle.The control objective is to provide robust altitudes and velocity tracking in the presence of model uncertainties and varying disturbances.A fuzzy-neural disturbance observer is developed to estimate uncertainties and disturbances,and the adaptive controller is synthesized by the dynamic surface approach combing with the observer.The tracking error at the steady state can be guaranteed to converge to inside of a small residue set which the size of the set can be an arbitrary small value.Simulation results demonstrate the effectiveness of the presented approach. | Li Zhou Shumin Fei | 2013 | Journal of Systems Engineering and Electronics2013，24，3： | 6 |
| 3 | A predictive functional control algorithm for multivariable systems with time delay显示文摘To improve the dynamic characteristics and the coupling capability,a new predictive functional control algorithm is proposed for strong coupling multivariable systems with time delay,which combines predictive functional control and decoupling control.First,a decoupling control algorithm is proposed,in which frst-order models with time delay are established by analyzing the amplitude-frequency and phase-frequency characteristics of the decoupled subject.Then,a controller is designed for the single-variable subjects after decoupling based on the principles of predictive functional control.The simulation results show that this proposed algorithm has less online computation time and faster tracking.It can provide a more effective control for complex multivariable systems. | Lei ZHOU Shumin FEI Jiacai HUANG Junyong ZHAI | 2013 | 控制理论与应用(英文版)2013，11，4： | 4 |
| 4 | Admissibility analysis and control synthesis for switched linear singular systems显示文摘The problem of admissibility analysis and control synthesis of discrete-time switched linear singular (SLS) systems for arbitrary switching laws is solved.By using the switched Lyapunov function approach,some new sufficient conditions under which the SLS system is admissible for arbitrary switching laws are derived in terms of linear matrix inequalities(LMIs).Based on the admissibility results,control synthesis is then to design switched state feedback and static output feedback controllers,guaranteeing that the resulting closed-loop system is admissible.The presented results can be viewed as the extensions of previous works on switched Lyapunov function approach from the regular switched systems to singular switched cases.Examples are provided to demonstrate the reduced conservatism and effectiveness of the proposed conditions. | Lin Jinxing Fei Shumin Shen Jiong | 2009 | Journal of Systems Engineering and Electronics2009，20，5： | 4 |

| 6 | Global stability of Cohen-Grossberg neural networks with time-varying and distributed delays显示文摘In this paper, the global asymptotic stability is investigated for a class of Cohen-Grossberg neural networks with time-varying and distributed delays. By using the Lyapunov-Krasovskii functional and equivalent descriptor form of the considered system, several delay-dependent sufficient conditions are obtained to guarantee the asymptotic stability of the addressed systems. These conditions are dependent on both time-varying and distributed delays and presented in terms of LMIs and therefore, the stability criteria of such systems can be checked readily by resorting to the Matlab LMI toolbox. Finally, an example is given to show the effectiveness and less conservatism of the proposed methods. | Tao LI Shumin FEI Qing ZHU | 2008 | 控制理论与应用(英文版)2008，6，4： | 3 |
| 7 | Robust stability and stabilization for uncertain discrete-time switched singular systems with time-varying delays显示文摘The problems of robust stability and stabilization via memoryless state feedback for a class of discrete-time switched singular systems with time-varying delays and linear fractional uncertainties are investigated.By constructing a novel switched Lyapunov-Krasovskii functional,a delay-dependent criterion for the unforced system to be regular,causal and uniformly asymptotically stable is established in terms of linear matrix inequalities(LMIs).An explicit expression for the desired memoryless state feedback stabilization controller is also given.The merits of the proposed criteria lie in their less conservativeness and relative simplicity,which are achieved by considering additionally useful terms(ignored in previous methods) when estimating the upper bound of the forward difference of the Lyapunov-Krasovskii functional and by avoiding utilizing any model augmentation transformation.Some numerical examples are provided to illustrate the validity of the proposed methods. | Jinxing Lin Shumin Fei Jiong Shen | 2010 | Journal of Systems Engineering and Electronics2010，21，4： | 2 |
| 8 | Impulsive controller design for nonlinear networked control systems with time delay and packet dropouts显示文摘The globally exponential stability of nonlinear impulsive networked control systems(NINCS) with time delay and packet dropouts is investigated.By applying Lyapunov function theory,sufficient conditions on the global exponential stability are derived by introducing a comparison system and estimating the corresponding Cauchy matrix.An impulsive controller is explicitly designed to achieve exponential stability and ensure state converge with a given decay rate for the system.The Lorenz oscillator system is presented as a numerical example to illustrate the theoretical results and effectiveness of the proposed controller design procedure. | Xianlin Zhao Shumin Fei Jinxing Lin | 2012 | Journal of Systems Engineering and Electronics2012，23，3： | 2 |
| 9 | Energy Efficient Data Collection in Hierarchical Wireless Sensor Networks显示文摘The majority of the energy consumption by the sensors is the energy requirement for data transmission in Wireless Sensor Networks (WSNs).Therefore,introducing mobile collectors to collect data instead of multi-hop data relay is essential.However,for many proposed data gathering approaches,long data delay is the main problem.Hence,the problem of how to decrease the energy consumption and the data delay needs to be solved.In this paper,a low delay data collection mechanism using multiple mobile collectors is proposed.First,a self-organization clustering algorithm is designed.Second,sensor nodes are organized into three-level clusters.Then a collection strategy based on the hierarchical structure is proposed,which includes two rules to dispatch mobile collectors rationally.Simulation results show that the proposed mechanism is superior to other existing approaches in terms of the reduction in energy expenditure and the decrease in data delay. | Zhang Chun Fei Shumin Zhou Xingpeng | 2012 | China Communications2012，9，9： | 2 |
| 10 | Adaptive integral dynamic surface control based on fully tuned radial basis function neural network显示文摘An adaptive integral dynamic surface control approach based on fully tuned radial basis function neural network (FTRBFNN) is presented for a general class of strict-feedback nonlinear systems,which may possess a wide class of uncertainties that are not linearly parameterized and do not have any prior knowledge of the bounding functions.FTRBFNN is employed to approximate the uncertainty online,and a systematic framework for adaptive controller design is given by dynamic surface control. The control algorithm has two outstanding features,namely,the neural network regulates the weights,width and center of Gaussian function simultaneously,which ensures the control system has perfect ability of restraining different unknown uncertainties and the integral term of tracking error introduced in the control law can eliminate the static error of the closed loop system effectively. As a result,high control precision can be achieved.All signals in the closed loop system can be guaranteed bounded by Lyapunov approach.Finally,simulation results demonstrate the validity of the control approach. | Li Zhou Shumin Fei Changsheng Jiang | 2010 | Journal of Systems Engineering and Electronics2010，21，6： | 2 |

| 12 | Control design approaches for nonlinear systems using multiple models显示文摘It is difficult to realize control for some complex nonlinear systems operated in different operating regions. Based on developing local models for different operating regions of the process, a novel algorithm using multiple models is proposed. It utilizes dynamic model bank to establish multiple local models, and their membership functions are defined according to respective regions. Then the nonlinear system is approximated to a weighted combination of the local models. The stability of the nonlinear system is proven. Finally, simulations are given to demonstrate the validity of the proposed method. | Junyong ZHAI Shumin FEI Feipeng DA | 2007 | 控制理论与应用(英文版)2007，5，3： | 1 |

| 17 | The CREB Regulated Transcription Coactivator 2 Suppresses HIV-1 Transcription by Preventing RNA PolⅡfrom Binding to HIV-1 LTR显示文摘The CREB-regulated transcriptional co-activators(CRTCs),including CRTC1,CRTC2 and CRTC3,enhance transcription of CREB-targeted genes.In addition to regulating host gene expression in response to cAMP,CRTCs also increase the infection of several viruses.While human immunodeficiency virus type 1(HIV-1)long terminal repeat(LTR)promoter harbors a cAMP response element and activation of the cAMP pathway promotes HIV-1 transcription,it remains unknown whether CRTCs have any effect on HIV-1 transcription and HIV-1 infection.Here,we reported that CRTC2 expression was induced by HIV-1 infection,but CRTC2 suppressed HIV-1 infection and diminished viral RNA expression.Mechanistic studies revealed that CRTC2 inhibited transcription from HIV-1 LTR and diminished RNA PolⅡoccupancy at the LTR independent of its association with CREB.Importantly,CRTC2 inhibits the activation of latent HIV-1.Together,these data suggest that in response to HIV-1 infection,cells increase the expression of CRTC2 which inhibits HIV-1 gene expression and may play a role in driving HIV-1 into latency. | Ling Ma Shumin Chen Zhen Wang Saisai Guo Jianyuan Zhao Dongrong Yi Quanjie Li Zhenlong Liu Fei Guo Xiaoyu Li Pingping Jia Jiwei Ding Chen Liang Shan Cen | 2021 | Virologica Sinica2021，36，4： | 1 |
| 18 | Robust adaptive control for uncertain systems with discrete and distributed delays显示文摘In this paper,a robust adaptive control scheme is proposed for the stabilization of uncertain linear systems with discrete and distributed delays and bounded perturbations. The uncertainty is assumed to be an unknown continuous function with norm-bounded restriction. The perturbation is sector-bounded. Combining with the liner matrix inequality method,neural networks and adaptive control,the control scheme ensures the exponential stability of the closed-loop system for any admissible uncertainty. | Qing ZHU Shumin FEI Tao LI Tianping ZHANG | 2008 | 控制理论与应用(英文版)2008，6，3： | 1 |
