| 摘 要： | 推导了多输入多输出网络控制系统的时滞离散时间数学模型，此模型包括了控制网络的网络延时．提出了一种新的网络控制系统稳定性分析方法，得到了使系统稳定的各网络延时应满足的条件．只要系统的网络延时满足这些条件，网络控制系统的极点便分布在复平面内的一个圆形区域内．若此圆形区域在单位圆内，网络控制系统就是稳定的．仿真实验验证了所提理论的有效性．

| Abstract: | A time delay discrete time model of multi-input and multi-output(MIMO) networked control system is derived which includes communication time delays of control networks.A new stability analysis method of networked control system is provided,and the conditions of network time delay which can make system stable are derived.If the network time delay of networked control system satisfies these conditions,the poles of networked control system are in a circular area on the complex plane.Networked control system is stable on condition that this circular area is in a(unit circle.) A simulation experiment illustrates the effectiveness of the presented theory. |
