    摘要:

    本文研究了一类存在执行器故障的非线性互联切换大系统的自适应模糊Backstepping容错控制.首先定义了一个分段右连续函数作为系统的切换信号，系统依据切换信号改变模型.不失一般性，考虑执行器发生两种类型的故障，即卡死故障和失效故障，通过模糊逻辑系统逼近未知非线性函数，并设计自适应模糊容错控制器补偿执行器故障给系统带来的影响.通过Lyapunov定理证明了系统及相关变量的有界性，并基于数值仿真，验证了所提出方法的有效性.

    Abstract:

    Adaptive fuzzy backstepping fault-tolerant control for a class of nonlinear large-scaleinterconnected switched systems with actuator failures is investigated in this paper.The system switches dynamically according to a piecewise right continuous function.Without loss of generality,stuck faults and the faults loss of effectiveness are considered.Fuzzy logic systems are utilized to approximate the unknown nonlinear functions.Considering the actuator failures,an adaptive fuzzy fault-tolerant controller is designed.It is proved that the proposed control method can guarantee that all the signals of the closed-loop system are bounded according to the Lyapunov theorem.A simulation example is presentedto demonstratethe effectiveness of the proposed control strategy.
