基于平均驻留时间的切换模型参考自适应控制方法的研究

摘要

The state tracking problem is investigated for switched systems with parametric uncertainty. This problem is converted into the stability problem of an error switched sys-tem. By using Lyapunov stability theory and the average dwell time method,some sufficient conditions are given to guarantee the stability of the error switched system. Finally,a simu-lation example is given to illustrate the proposed method.%研究切换系统的被控对象存在参数不确定性的情形,解决切换模型参考自适控制系统的状态跟踪控制问题.通过建立误差切换系统,根据李雅普诺夫稳定性理论,利用平均驻留时间(ADT)方法得到充分条件,通过设计切换规则,解决闭环系统的状态跟踪问题,并且通过仿真验证了方法的有效性.
