| 摘 要： | 研究一类具有时延不确定性网络化控制系统的鲁棒容错控制问题.基于网络化控制系统时延模型,应用Lyapunov稳定性理论和LMI方法,采用输出反馈控制策略,推证出保证闭环网络化控制系统在执行器或传感器发生失效故障时仍渐进稳定的的充分条件,给出容错控制器的设计方法,最后以仿真算例得到系统零状态响应曲线,分析曲线所得结论说明此方法的可行性和有效性.

| Abstract: | The problem of robust fault-tolerant control for a class of networked control systems with uncertain time-delay was studied.Based on the time-delay model for networked control systems,Lyapunov stability theory,and linear matrix inequality(LMI) method,a sufficient condition was derived by using output feedback for ensuring the asymptotic stability of the close-looped NCS against the failures in sensors or actuators,and a design method of robust fault-tolerant controller was given by means of solving several ... |
