摘要
本文利用多存储函数方法研究了一类非线性切换系统的拟无源、反馈拟无源问题.首先,提出了该类非线性切换系统的拟无源性概念.并设计了一个状态依赖切换律使切换非线性系统具有拟无源性.其次,通过状态依赖切换率和状态反馈控制器的设计实现非线性切换系统的拟无源化.最后,通过一个数值例子说明该方法的有效性.
This paper studies the issues of quasi-passivity,feedback quasi-passification for a class of switched nonlinear system using multiple storage functions.Firstly,a quasi-passivity concept for a switched nonlinear system is proposed.and,a state-dependent switching law is designed to render a switched nonlinear system quasi-passive.Secondly,quasi-passification is achieved by the design of a state-dependent switching law and state feedback controllers for switched nonlinear systems.Finally,a numerical example is presented to illustrate the effectiveness of the proposed approach.
