摘要: 研究了含有结构参数扰动的一类非线性不确定切换系统的鲁棒可靠控制问题.假定非线性项满足范数有界性条件,参数不确定性可以是时变的.当执行器“严重失效”——未失效执行器的部分不能镇定原系统时,利用多Lyapunav函数法,给出了混杂状态反馈可靠控制器的设计, 使得闭环系统对所有可能的不确定性和所有允许的执行器失效,在所设计的混杂状态反馈可靠控制器下是渐近稳定的.仿真结果验证了结论的有效性.

Abstract: The reliable robust control is studied for a class of uncertain switched nonlinear systems disturbed by uncertain structural parameters. It is assumed that the nonlinear terms satisfy the norm-bounded condition and the parameter uncertainty is time-variable. Based on multiple-Lyapunov function method, the design of hybrid state feedback-reliable controllers is given such that the corresponding closed-loop system is globally asymptotically stable for all admissible uncertainties and actuator failures. The simulation result demonstrated the effectiveness of the proposed approaches.
