Abstract

In this paper, the problem of robust fault-tolerant control for a kind of multi time-delay LTI systems is studied based on the Riccati function and Lyapunov´s steady theorem. The output feedback control law with multi time-delay is put forward and the design method of fault-tolerant controller with integrity against actuator and sensor failures is proposed. Sufficient condition of integrity against actuator and sensor failures is given. Finally, the design method is applied and the results demonstrate that the method proposed by this paper is more effective and more stable than that of output feedback without time-delay.
