| 摘 要： | 针对网络控制系统中网络延时对系统的影响，分析了两种网络延时的特点，建立了网络时延预估模型，重点对从控制器到执行器的网络延时的不确定性进行了预估分析，进而将不确定性延时的网络控制系统转换为确定时延时，并且通过分析系统的时滞离散方程的矩阵特征值的特性，给出了离散系统方程的稳定性条件。最后通过数值例子验证了该方法的有效性。

| Abstract: | Against the effect on Networked Control System（NCS）caused by networked time-delay, it analyzes character of two different time-delays, builds a predictor model to networked time-delay in this paper that is emphasized on uncer-tainty of delay from control to actuator in NCS and makes the uncertainty time-delay to be certain. And it analyzes the characteristic value of discrete function with delay for the NCS, gets the stability conditions. Finally, it proves the method right by example. |
