摘要
本文研究了异步切换系统的有限时间界限和保性能控制问题.为减少冗余信息传输和缓解传感器节点的数据拥塞,提出事件触发方案(ETS)和循环协议(RRP),旨在确保系统表现良好的动态特性的同时减少通信资源.在有限时间控制领域,采用允许边依赖平均停留时间(AED-ADT)方法设计切换信号.该方法涉及慢速AED-ADT切换和快速AED-ADT切换,分别适用于被控系统在异步切换间隔内的有限时间稳定和有限时间不稳定情况.通过构造双模态依赖的李雅普诺夫函数,得到切换系统的有限时间有界准则和控制器增益.最后,通过一个升降压电路模型验证了所提结果的有效性.
Abstract
This paper focuses on addressing the problems of finite-time boundedness and guaranteed cost control in switched systems under asynchronous switching.To reduce redundant information transmission and alleviate data congestion of sensor nodes,two schemes are proposed:the event-triggered scheme(ETS)and the round-robin protocol(RRP).These schemes are designed to ensure that the system exhibits good dynamic characteristics while reducing communication resources.In the field of finite-time control,a switching signal is designed using the admissible edge-dependent average dwell time(AED-ADT)method.This method involves a slow AED-ADT switching and a fast AED-ADT switching,which are respectively suitable for finite-time stable and finite-time unstable situations of the controlled system within the asynchronous switching interval.By constructing a double-mode dependent Lyapunov function,the finite-time bounded criterion and the controller gain of the switched systems are obtained.Finally,the validity of the proposed results is showcased by implementing a buck-boost voltage circuit model.
