摘要： 利用共同Lyapunov函数技术,研究了一类含有结构参数不确定性和未知非线性扰动的非线性切换系统的鲁棒容错控制问题·给出了各个子系统的状态反馈控制器的设计,使得闭环系统对于结构参数不确定性和未知非线性扰动具有鲁棒性,并且在任意切换下保证闭环系统是全局渐近稳定的·同时当系统的执行器失效时,通过预先给定的失效集,使得闭环系统对于所有发生在给定失效集的执行器失效,在任意切换下是全局渐近稳定的·最后用具体的例子验证了本文设计方法的可行性和有效性·

Abstract: The problem of robust fault-tolerant control for a class of switched nonlinear systems with structural parameters uncertainty and unknown nonlinear disturbance is studied. The purpose is to design individual state feedback controller by means of common Lyapunov function to guarantee globally asymptotic stability under arbitrary switching. In the case of actuator failures, a pre-specified failure set of actuators is introduced and the closed-loop systems are shown to be globally asymptotically stable for all possible actuator failures. Finally, an illustrative example is used to demonstrate the feasibility of the proposed approach to design.
