摘　　要：针对事件触发机制下网络化系统的输出反馈耗散控制问题进行研究。首先,引入事件触发机制来减少有限带宽的影响,节约系统资源;其次,考虑网络化系统中存在的外部干扰,利用输入时滞法建立了基于事件触发机制的时滞系统模型;然后,构造一种时滞相关的Lyapunov-Krasovskii泛函,利用改进的积分处理方法推导出了保证闭环系统严格耗散性能的充分条件,并采用锥补线性化算法求出输出反馈控制器增益和事件触发参数矩阵;最后,通过数值仿真验证了所提方法的有效性与优越性。The output feedback dissipative control problem of networked systems with event-triggered mechanism is studied.Firstly,an event-triggered mechanism is introduced to reduce the impact of limited bandwidth and save system resources.Secondly,considering the external disturbances in networked systems,a time-delay system model based on event-triggered mechanism is established by using the input time-delay method.Then,a delay-dependent Lyapunov-Krasovskii functional is constructed,and sufficient conditions for strict dissipation performance of the closed-loop system are derived by using the improved integral processing method.The gain of the output feedback controller and the event-triggered parameter matrix are obtained by using the cone-complement linearization algorithm.Finally,the effectiveness and superiority of the proposed method are verified by numerical simulations.
