摘要: 针对不确定时延的网络控制系统,传感器采用时间驱动,控制器和执行器采用事件驱动,将系统建模为一类不确定性的线性离散系统.通过构造李雅普诺夫函数,结合线性矩阵不等式(LMI)的有关知识,对系统的稳定性进行分析,给出了系统稳定的充分条件.给出算例,用MATLAB进行仿真,证明了结论的有效性.

关键词: 网络控制系统;线性矩阵不等式;稳定性;不确定时延

Abstract: Abstract:Considering the uncertain delay of networked control systems(NCS),with the sensor node of NCS time-driven.and acuatorand controllers event.driven,the networke control systems was modeled as an uncertain discrete liner system.Then it constructed one lyaupon function,using the relevant knowledge of liner matrix inequalities (LMIs),analyzing the stability of the system,and giving one suficient condition for system stability.At last,an example was given.The simulation results verify the effectiveness of the method.

Key words: networked control systems(NCS);liner matrix inequality;stability;uncertain delay
