摘　　要：针对一类具有随机大时延(大于一个采样周期)的网络控制系统,通过对系统的离散化,从理论上分析了系统的稳定性.利用分割的思想处理随机的网络时延,采用离线控制器设计与在线切换规律设计相结合的方法,给出了系统基于控制器切换技术的稳定的梯度算法.仿真算例说明了结论与算法的正确性.The stability of networked control systems with larger delays is studied. The analysis of networked control systems is carried out in theory by dispersing the systems. The stochastic networked-induced delay is dealt with by the idea of partition. Based on this idea, a method of combining controller design offline with switching law online is proposed and a gradient algorithm is developed for the system. Finally, a simulation example shows the validity of the algorithm.
