摘要： 基于数据包丢失现象和网络诱导时延的存在,当传感器采用时间驱动,控制器和执行器采用事件驱动时,将被控制对象为广义系统的网络控制系统建成异步动态的离散系统模型.利用李雅普诺夫函数方法和线性矩阵不等式方法,给出了广义网络控制系统指数稳定的充分条件.在判定闭环网络控制系统指数稳定的同时,通过求解线性不等式获得了使系统指数稳定的状态反馈控制律.最后的实例表明方法的可行性.

Abstract: To solve the problems of data packet dropout and network-induced time delay, the networked control system for something as a singular system is modeled to become an asynchronously dynamical discrete system if the relevant sensors and controllers/actuators are time-driven and event-driven, respectively. Then, by Lyapunov function and linear matrix inequality (LMI), the sufficient conditions are given to make the singular networked control system exponentially stable. With the closed-loop networked control system exponentially stabilized, the state feedback control law which can make the system exponentially stable is also obtained by solving some LMIs. An example is given to illustrate the effectiveness of the proposed method.
