非理想网络环境下线性控制系统的稳定性分析

摘要

This paper studies problems of stability for linear control systems following a interval time-varying delay system. A new Lyapunov-Krasovskii functional, which makes good use of the information of the lower and upper bounds of the interval time-varying delay, is used to drive a less conservative stability criterion. An example is given to show the effectiveness of the proposed method.%针对一种具有非理想网络状态的网络控制系统，建立了区间时滞系统模型，研究了系统的稳定性问题．通过构造一个包含时滞上下界信息的Lyapunonv—Krasovskii泛函，获得了一个新的稳定性判据．数值算例表明，所得结果具有较小的保守性．
