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.针对一类含有时变、范数有界参数不确定奇异系统,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正则、无脉冲,且保持有限时间状态稳定,给出了有限时间容错控制器存在的充分条件和设计方法,该方法通过解线性矩阵不等式即可得到容错控制器的设计结果.数值算例验证了该容错控制设计方法的有效性.

关 键 词:容错控制  有限时间稳定  线性矩阵不等式  参数不确定  奇异系统  有限  时间  容错控制器设计  uncertain  singular  systems  finite  time  controller  有效性  验证  数值算例  结果  线性矩阵不等式方法  设计方法  充分条件  存在  状态稳定  无脉冲  正则  闭环系统

Abstract:We focused the problems of fault-tolerant control with finite time in uncertain singular system, whose class is with parameter uncertainties and norm-bounded. Based on 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 regular, impulse-free and finite-time stability. A. sufficient condition for the existence of finite-time fault-tolerant controller and designing technique were derived. This method can-obtain the designed result of fault-tolerant controller by using the linear matrix inequality. A numerical example shows the validity of the proposed method.
Keywords:fault-tolerant control  finite-time stability  linear matrix inequality(LMI)
