| 摘 要： | 考虑了一类标称系统存在共同Lyapunov函数的不确定非线性切换系统的鲁棒状态观测器的设计问题。系统具有满足Lipschitz条件的非线性项，不确定项不满足匹配条件，设计出了该系统在任意切换策略下的鲁棒渐近状态观测器。仿真结果表明所设计观测器的有效性。

| Abstract: | The problem of the design of robust state observer for a class of switched nonlinear systems with uncertainty whose nominal systems exist common Lyapunov function is considered. The nonlinear term satisfies Lipschitz condition, and the uncertainty does not satisfy the so called matching condition. The asymptotically robust observer is designed under arbitrary switching law. Simulation is given to show the validity of the state observer. |
