Fault-tolerant control for linear system with actuator and sensor simultaneous faults

This paper studies a continuous linear control system with actuator and sensor faults for its guaranteed cost control and H_∞ control. When the actuator and the sensor synchronize fault, in view of the actuator and the sensor performance´s quality increase the quality of normal actuator and sensor under guarantee the system stabled, enables the system to have certain performance and along with increasing the normal actuator and the sensor system´s performance will no less than the system with less normal actuator and sensor. The developed theory is illustrated by a simulation example, which shows the validity of the proposed method and the necessity of such a satisfactory fault-tolerant control.
