摘要
针对网络化系统研究具有模态依赖平均驻留时间(MDADT)和异步的线性切换系统的周期动态事件触发H∞控制.与已有切换系统事件触发方式不同,周期动态事件触发引入动态事件触发参数,且具有最小的事件触发间隔下界,在降低数据发送数量的同时,能够有效避免奇诺行为;利用MDADT方法和多Lyapunov函数技术,给出闭环系统具有指数稳定和H∞加权性能的充分条件;在此基础上,针对周期动态事件触发机制中可能存在的异步问题,提出相应的控制器设计准则.最后,通过算例验证所得结果的优越性.
This paper is concerned with periodic dynamic event-triggered H∞ control for networked switched linear systems with both mode-dependent average dwell time(MDADT) and asynchronous switching. Compared with the existing event-triggered results of the switched systems, the periodic dynamic event-triggered scheme introduces dynamic event-triggered parameters and has the minimum lower bound of event-triggered interval, which can effectively reduce the number of data packages and avoid the Zeno behavior. By using the MDADT approach and the multiple Lyapunov functions technique, sufficient conditions are proposed so that the close-loop system is exponential stable with a weighted H∞ performance. Furthermore, the corresponding criterion is proposed to design a set of controllers for the switched system with asynchronism. Finally, an example is provided to verify the superiority of the acquired results.
