中文摘要: 研究了具有切换拓扑的离散时间多智能体系统的事件触发H∞滤波问题.构造了一种新的分布式事件触发控制方案,以确定是否每个智能体应该传输当前采样数据到滤波器,从而有效的节约网络资源.考虑到网络诱导时延的存在,同时利用马尔可夫过程对网络拓扑的切换进行建模,采用事件触发控制方案并结合所提的H∞滤波器,将分布式滤波误差系统建模成一个具有多时变时延的闭环系统.利用包含多区间上下界信息的Lyapunov-Krasovskii泛函和线性矩阵不等式方法,得到了保证闭环系统实现具有H∞性能指标渐近稳定性的一些充分条件和H∞滤波器参数的设计方法.最后,通过两个数值算例说明了该方法的有效性.
Abstract:This study investigates event-triggered H∞ filtering problem for discrete-time multi-agent systems with switching topologies. A novel distributed event-triggered control scheme is constructed to determine whether each agent should transmit the current sampled data to the filter, thus effectively save network resources. Considering the existence of network-induced delay and modeling the switching of network topologies by a Markov process, the distributed filtering error system is modeled as a closed-loop system with multiple time-varying delays by using the event-triggered control scheme and the proposed H∞ filter. By employing Lyapunov-Krasovskii functional and linear matrix inequality method with multi-interval upper and lower bounds information, some sufficient conditions and the design method of H∞ filter parameters are obtained to guarantee the closed-loop system to achieve asymptotic stability with an H∞ performance index. Finally, two numerical examples are given to illustrate the effectiveness of the proposed method.
