| 摘 要： | 讨论了不确定线性奇异系统的有限时间容错控制问题. 针对一类具有时变外部扰动的不确定奇异系统,运用线性矩阵不等式方法(LMI),设计了鲁棒容错状态反馈控制律,使得当奇异系统执行器发生故障时,故障闭环系统仍然是无脉冲的,且保持有限时间状态稳定,同时也给出了有限时间容错控制器存在的充分条件和设计方法,数值算例验证了该容错控制设计方法的有效性.

| Abstract: | The problems of finite-time fault-tolerant control for uncertain singular systems with exogenous disturbance are discussed.The disturbance is assumed time-varying and norm-bounded.Based on linear matrix inequality(LMI),LMI a robust fault-tolerant state feedback controller is designed against actuator failures.The controller designed can guarantee that the resultant closed-loop system is impulse-free and finite-time stability.A sufficient condition for the existence of finite-time fault-tolerant controller a... |
