Adaptive Fault-tolerant Control for Time-delay Systems with Saturation Nonlinearity

摘要：

　　This paper studies the problem of designing adaptive fault-tolerant controllers for linear time-delay systems with actuator saturation.New methods for designing indirect adaptive fault-tolerant controllers via state feedback are presented for actuator fault compensations.Based on the on-line estimation of eventual faults,the adaptive fault-tolerant controller parameters are updating automatically to compensate the fault effects on systems.The designs are developed in the framework of linear matrix inequality (LMI) approach,which can enlarge the domain of asymptotic stability of closed-loop systems in the cases of actuator saturation and actuator failures.An example is given to illustrate the efficiency of the design method.
