摘要：
针对网络控制系统中网络存在时延问题，采用随机时延建模方法，将不同负载情况下的时延表示成区间变量，通过具有范数有界不确定性的离散Markov跳变系统描述系统模型，进行系统的随机稳定性分析，基于线性矩阵不等式设计状态反馈控制器.最后通过数值仿真验证控制器设计算法的有效性.

Abstract: Regarding the problem with the network delay of the network control systems, the random time delay modeling method is used. First, interval delay under different conditions was put into a range of variables. Secord, the state feedback controller was designed, based on linear matrix inequality, Third, by describing the system model with the norm bounded by the uncertainty of discrete Markov jump systems, the random stability of the system was analyzed. Numerical simulation verifies the effectiveness of the algorithm.

Key words: network control system; interval delay; Markov jump systems; linear matrix inequalities; controller
