| 摘 要： | 针对网络只存在于传感器节点与控制器节点之间的多输入多输出(MIMO)网络控制系统,研究了系统建模和稳定性问题.设传感器节点和控制器节点均为时间驱动,且它们的采样存在着固定的时间差,网络诱导时延的上界大于一个采样周期,建立了此类网络控制系统的模型.基于Lyapunov函数和线性矩阵不等式(LMIs)方法,给出了闭环系统渐近稳定的充分条件.仿真表明本文的方法是有效的.

| Abstract: | Considering the MIMO networked control systems with the sensors and controller interconnected by network,the model and stability are studied.Suppose the sensor nodes and the controller node are time-driven with fixed time difference (among) their sampling time,the maximum network-induced delay is larger than one sample period; the model of the networked control system is given.Based on the Lyapunov function and linear matrix inequalities (LMIs),the sufficient condition subject to the asymptotic stability of the close loop system is derived.The simulation verified the validity of the method. |
