摘　　要：　本文基于Riccati方程和Lyapunov稳定性理论,讨论了状态反馈闭环系统中传感器故障容错控制问题,研究了时滞不确定系统对传感器失效具有完整性的鲁棒控制律的设计方法,给出了系统渐近稳定的充分条件.设计实例和仿真结果验证了该方法的有效性.Based on the Riccati equation and the Lyapunov stability theory, the problem of faulttolerance control against sensor failures in linear state feedback systems is discussed , and the design of Robust control laws for uncertain timedelay systems with sensor failures is studied.A sufficient condition for the system to be asymptotically stable is presented. An illustrative example and the simulation result are provided to demonstrate the effectiveness of the proposed design method.
