In this article, a switched sampled output adaptive observer for a class of switched nonlinearly parameterized systems is designed. Since the switching may occur during the sampling intervals while the sampled output only updates at sampling instants, the asynchronous switching phenomenon arises. Then, a collection of matched and mismatched corrective terms are introduced to deal with the asynchronous switching phenomenon based on sampled outputs and the designed observer. Moreover, some sufficient conditions are derived to achieve the boundedness of observation and parameter estimation errors based on an improved average dwell time method. Finally, the effectiveness of the theoretical result in this article is demonstrated through a simulation example.

一类非同步切换非线性参数化系统的切换采样输出自适应观测器设计

在本文中，设计了一类开关非线性参数化系统的开关采样输出自适应观测器。由于切换可能发生在采样间隔内，而采样输出仅在采样时刻更新，因此会出现异步切换现象。然后，根据采样的输出和设计的观察器，引入了一组匹配和不匹配的校正项来处理异步切换现象。此外，基于改进的平均停留时间方法，得出了一些足够的条件来实现观测值和参数估计误差的有界性。最后，通过一个仿真实例证明了本文理论结果的有效性。
