| 摘 要： | 针对一类非线性扰动项不满足匹配条件的蚤确定切换系统鲁棒动态输出反馈镇定问题，采用单李雅普诺夫函数方法和变量替换方法，研究了状态矩阵和控制输入矩阵同时带有未知、时变但有界的不确定性，且有外界干扰的切换系统，给出了不确定切换系统鲁棒可稳的充分备件。仿真结果表明，所设计的动态输出反馈控制器及相应的切换策略保证了闭环系统渐近稳定。

| Abstract: | The problem of robust dynamic output feedback stabilization for a class of uncertain switched systems is considered. The nonlinear disturbances do not satisfy matching condition. By using single Lyapunov function technique and change of variable method, sufficient conditions of robust stabilization for switched systems are obtained under the assumption that the parameter uncertainties are time-varying and unknown but norm-bounded. The simulation results show that the designed controllers and switching laws guarantee the closed-loop systems asymptotically stable. |
