Abstract
In this article, a decentralized adaptive fault-tolerant control(FTC) scheme is proposed for a class of large-scale nonlinear systems with unknown time-varying parameters, actuator faults and unknown strong interconnections. Firstaccording to the fundamental traits of Gaussian function for the interconnection terms, the interference of interconnection terms to the system is eliminated effectively. Second, By employing command filter technique and adaptive neural control, the "singular" and "explosion of complex" problems in the backstepping procedure are circumvented. It is shown that all the closed-loop signals are bounded and the tracking errors converge to arbitrarily small residual sets. Finally, the effectiveness of decentralized adaptive fault-tolerant control scheme is demonstrated by simulation results.
