摘要： 针对一类具有时变时延的广义网络控制系统,研究了系统的稳定性和控制器设计问题.假定广义网络控制系统中的传感器采用时钟驱动,控制器和执行器采用事件驱动,时延小于一个采样周期且是时变的.首先对广义网络控制系统进行建模,利用李雅普诺夫函数和线性矩阵不等式方法,给出系统渐近稳定的充分条件.利用Matlab LMI工具箱,可在判定系统稳定的同时,得到使系统稳定的相应的状态反馈控制器.

Abstract: The problems of stability and controller design for a class of singular networked control systems (NCS) with time-varying delay are considered. The sensor node is assumed to be time-driven, the controller and actuator are event-driven, and the time-varying delay is less than one sampling period. First, the model of the singular NCS is constructed. Then, using Lyapunov function and linear matrix inequality method, the sufficient condition of asymptotic stability for the singular NCS is given, and the state feedback control law can be obtained at the same time by using Matlab LMI toolbox.
