摘　　要：研究了离散时滞系统的完整性设计问题 ,提出一种基于Lyapunov方程的对传感器失效故障具有完整性的容错控制器设计方法 ,进而讨论了参数不确定离散时滞系统的鲁棒容错控制问题 ,给出了鲁棒容错控制器的设计步骤 ,并讨论了执行器失效的情况 。The problem of integrity design for discrete time delay systems is studied. The design method of fault tolerant controller possessing integrity against sensor failures is proposed on the basis of Lyapunov equation. The problem of robust fault tolerant control for uncertain discrete time delay systems is discussed. The design procedure of robust fault tolerant controller is given. The situation of actuator failures is discussed. Finally, an illustrative example and simulation results are given to demonstrate the effectiveness of the proposed method.
