摘　　要：针对线性不确定时滞系统,提出了考虑传感器和执行器故障的一类鲁棒容错控制问题.通过采用带有时滞项的状态反馈,利用Riccati方程和Lyapunov稳定性理论,分别给出了传感器故障、执行器故障和同时故障模式下的容错控制条件.最后,给出仿真数例以说明该方法的可行性和有效性.The robust fault-tolerant control problem of a kind of linear uncertain time-delay system with sen sor and actuator failures is studied. With time-delay state feedback, it proposes the fault-tolerant control conditions for various failures in terms of Riccati equation and Lyapunov stability theory. At the end of this paper,it gives a simulation example to illustrate the feasibility and effectiveness of the proposed approach.
