同时受时延与丢包干扰的网络控制系统的分析与控制

Analysis and control of networked control system with delay and packet dropouts

主要研究同时存在网络时延和网络丢包情形下的网络控制系统的分析与综合问题。运用输入时延方法,通过将同时受到数据丢包和网络时延干扰的网络控制系统转化为一个延时系统,基于矩阵不等式理论和李亚普诺夫方法分析时延丢包网络控制系统的稳定性。在稳定性结果的基础上,进一步提出一种新的控制器设计方案,最后通过一个仿真例子表明所提出的设计方案的有效性。

This paper discussed how to do analysis and synthesis in networked control system with delay and packet dropouts. Input delay method was employed to change the networked control system into delay system and matrix inequality theory and Lyapunov function were employed to analyze the stability of the changed system.
