Abstract In this paper, a switched adaptive observer for a class of switched uncertain nonlinear systems is designed by using an average dwell time (ADT) method. Due to that switching unknown parameters lead to different coordinates transformation for different subsystems, some new dwell-time conditions are provided by an improved ADT method. Also, the boundedness of all signals is ensured by a well defined persistent excitation condition under a class of switching signals with ADT. Finally, the effectiveness of the theoretical results in this paper is demonstrated through a simulation example.

一类切换不确定非线性系统的切换自适应观测器设计

摘要 本文利用平均驻留时间(ADT)方法设计了一类切换式不确定非线性系统的切换式自适应观测器。由于切换未知参数导致不同子系统的坐标变换不同，改进的ADT方法提供了一些新的停留时间条件。此外，在具有 ADT 的一类开关信号下，通过明确定义的持久激励条件确保所有信号的有界性。最后，通过仿真实例证明了本文理论结果的有效性。
