| Abstract: | This paper focuses on the problem of robust fault-tolerant control for uncertain systems with time-delay. In the circumstances of the sensor failures or the actuator failures, on the basis of the linear matrix inequality (LMI), the sufficient conditions for the systems possessing integrity against the sensor failures or the actuator failures are given, and the design method of the controller is proposed. This method can obtain the designed result of fault-tolerant controller by using the linear matrix inequality,and avoids the iterative process of the methods in existence.An illustrative example and some simulation results are given to demonstrate the effectiveness of the proposed method. |
