Robust Fault-Tolerant Control of Uncertain Systems with State and Control Time-delay

This paper focuses on the problem of robust fault tolerant control for the uncertain systems with state and control time delay.Based on Lyapunov asymptotic stability theory,the robust stabilization of uncertain time delay systems is discussed against sensor or actuator failures,the sufficient conditions of closed loop systems possessing robust faulty tolerant characteristics are given.With an auxiliary algebraic Riccati equation a controller design method is given.The results of a simulation example demonstrate the feasibility of the proposed design method.
