摘　　要：主要考虑网络化控制系统中通信网络和控制系统的耦合问题,研究了基于事件触发机制的控制与通信的协同设计问题。首先,建立了基于通信网络的事件触发控制模型,通过分析控制系统模型和通信网络拥塞控制模型设计了新的事件触发条件;然后,运用(Lyapunov-Krasovskii,L-K)泛函和LMI,分析了网络化控制系统的H?性能,并进行了H?控制器的设计;最后,通过仿真实例表明所得结论的正确性。Considering the coupled problems of communication network and control systems for network control systems, co-design of control and communication based on event-triggered scheme for network control systems is studied. First, the model of event-triggered control based on the communication network is built, by analysing the model of control systems and congestion control of the communication network, a novel event-triggered condition is presented. And then, by applying the Lyapunov-Krasovskii functional approach and linear matrix inequality, the H∞ performance of network control systems are analyzed, and the H∞ controller are designed. Finally, a numerical example shows the correctness of this conclusion.
