摘　　要：对具有不确定参数的连续控制系统,针对传感器失效,研究了鲁棒容错控制器的设计问题。由于系统往往状态不可直接获得,本文给出了当系统采用Luenberger降维观测器实现状态反馈时,既保证闭环系统鲁棒稳定,又保证系统具有完整性的鲁棒容错控制器的设计方法。数值算例表明了文中提出的控制器设计方法的有效性。A design method of robust fault tolerance for uncertain linear systems with sensor failures is discussed in this paper. As the states of the linear system can not be observed directly, a Luenberger reduced order observer is used to realize the state feedback. Based on it, a design method of robust fault tolerant controller is given to guarantee the robust stability and the integrity for the closed loop system. A numerical example is given to illustrate the design procedure and its effectiveness.
