Abstract: In order to solve the [H∞] output feedback control problem of event-triggered Markov type systems, Wirtinger’s inequality is used to estimate the upper bound of the weak infinitesimal operator of Lyapunov function by constructing Lyapunov function containing event- triggered and quantized output information. The stability criterion of event-triggered Markov network closed-loop system is obtained, and the output feedback controller design method is given. It satisfies the level of [H∞] disturbance suppression, which can effectively overcome the impact of disturbance on the system.

摘要: 针对事件驱动马尔可夫型网络系统的输出反馈[H∞]控制问题,通过构造包含事件驱动和量化输出信息的李雅普诺夫函数,采用Wirtinger’s不等式估计李雅普诺夫函数的弱无穷小算子的上界,从而获得事情驱动马尔可夫型网络闭环系统稳定性判据,并给出满足[H∞]扰动抑制水平的输出反馈控制器设计方法,有效地克服了扰动给系统带来的影响。数值例子验证所提出的方法的有效性。
