具有时延及数据包丢失的广义网络控制系统稳定性分析

对一类具有时延及数据包丢失的正则、无脉冲广义网络控制系统进行分析,其中传感器采用时钟驱动,控制器和执行器采用事件驱动.假设传输时延小于一个采样周期,数据包传输成功率一定,将广义网络控制系统进行建模为异步动态系统,同时利用李雅普诺夫函数和线性矩阵不等式方法,给出系统稳定的充分条件.借助于Matlab LMI工具箱,可在判定系统稳定的同时,获得使系统稳定的状态反馈控制律.最后的仿真实例表明该方法的可行性.

Stability of Singular Networked Control System with Delay and Data Packet Dropout

The regular and impulsive-free singular NCSs(networked control systems) with networked-induced delay and data packet dropout are discussed,where the sensor node is time-driven but the controller and executor are event-driven.Assuming that the transfer delay is shorter than the sampling period and the data packets can be transferred successfully at a constant rate,the singular NCS can be modeled as an asynchronous dynamical system.With the Lyapunov function and LMI(linear matrix inequality) method,the suffic...
