Design of robust H_∞ fault-tolerant output feedback control based on LMI

For linear uncertain systems with actuator faults,the problem of robust fault-tolerant H∞ dynamic output feedback control was studied.Based on an actuator failure model with continuous gain,the sufficient condition for dynamic output feedback H∞ robust fault-tolerant controllers was proposed by using a linear matrix inequality(LMI) approach,and the corresponding design method of a dynamic output feedback H∞ controller was given.The proposed controller not only enables the system to keep robust stabilization but also achieves the given H∞ performance.A simulation experiment shows that the proposed method is effective.
