Popis: | In this paper, authors gave an improved condition for set invariance for neutral time-delay systems with actuator saturation and fault. Methods for designing indirect adaptive fault-tolerant controllers are given 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 improved condition for set invariance are developed in the framework of linear matrix inequality (LMI) approach, which can guarantee that the domain of asymptotic stability of closed-loop systems is enlarged as possible in the cases of actuator saturation, time-delay and actuator failures. |
