The problem of robust fault-tolerant control for a class of uncertain linear systems with state and control delay is studied. Considering both failure of sensor and actuator, the uncertain delay system is discussed based on Lyapunov asymptotic stability theory The sufficient conditions for the robust fault-tolerant behavior of the closed-loop system are given. The design method of the controller is given through the construction of an algebraic Riccati equation. Simulation results show that the proposed method is feasible
