| 摘 要： | 针对在实际工程系统中量测设备在经济性与使用性上存在限制,系统状态通常不能完全观测的问题,考虑了含李普希兹非线性干扰项的切换系统观测器设计问题,通过设计适当的切换策略,提出了一种全局二次稳定的观测器设计方案。该方案适用于有限和无限切换系统,其主要结果以线性矩阵不等式(LMI)的形式表达。该方案简单、易实现,仿真算例验证了其有效性。

| Abstract: | To the problem that the state variables of systems usually are not fully observed with observering equipment,the observer design for Lipschitz switched nonlinear systems is considered.By proposing a proper switching strategy,a quadratically stable observer which can be used for both finite and infinite switched nonlinear systems is designed.The main result is given in the form of linear matrix inequality so that it can be easily implemented.Simulations show the correctness and effectiveness of the presented algorithms. |
