基于反馈数据时延的网络控制系统稳定性研究

Research on the stability of networked control systems based on the time delay of feedback data

先就时延、丢包对网络化控制系统稳定性分别进行了分析,进而考虑把网络传输引发的时延和丢包同时包含进输入时延中,以此为基础建立了同时存在时延及丢包现象的网络化控制系统模型,并借助李雅普诺夫函数、线性不等式矩阵方程分析及锥补线性化算法,证明了基于反馈数据时延的网络控制系统模型的稳定性,有效解决了同时存在时延及丢包现象的网络化控制系统的稳定控制问题。

This paper firstly analyzes the influence of the delay and packet loss on networked control system stability, and then considers including the network transmission delay and packet loss caused by both input in the extension. On this basis the control system model of network delay and packet loss phenomenon at the same time was established, and using Lyapunov function and linear matrix inequali- ty equation stability analysis and theory system model, the stability of networked control systems based on the time delay of feedback da- ta is proved, effectively solving the stable control problem of network delay and packet loss and control system.
