非理想网络环境下线性控制系统的稳定性分析

Stability Analysis for Linear Control Systems with Non-deal Network Quality of Services

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.

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.
