摘要: 研究了切换随机系统的事件触发控制问题,为避免Zeno行为和减少不必要的通信传输,提出一种基于采样数据的事件触发控制方案。首先,假设控制器可以获取系统状态和开关信号的同步采样信息。利用合并切换信号技术,将闭环系统建模为具有状态误差和增广切换信号的切换随机系统。然后,通过多重李雅普诺夫函数方法和范数放缩,获得了充分的均方指数稳定性条件。同时,给出了切换随机系统的稳定控制器设计方法。最后,通过数值仿真验证了方法的有效性。

Abstract: In this paper, the event-triggered control problem of switched stochastic systems is discussed. In order to avoid Zeno behavior and reduce unnecessary communication transmission, an event-triggered control scheme based on sampled data is proposed. Firstly, it is assumed that the controller can obtain the synchronous sampling information of the system states and switching signals. The closed-loop system is modeled as a switched stochastic system with state errors and augmented switching signals by using the merging switching signal technique. Then, through multiple Lyapunov function approach and norm scaling, sufficient mean square exponential stability conditions are obtained. Also, the stabilizing controller design approach of switched stochastic systems is given. Finally, the effectiveness of the method is verified by numerical simulation.


Key words: switched stochastic system; average dwell time; event-triggered control; mean-square exponential stability
