时延网络控制系统的稳定性分析

Stability Analysis of Networked Control Systems With Delay

为保证闭环系统的全局渐进稳定性,系统的时延必须是有界的。本文中讨论了具有网络诱导时延的网络控制系统的模型,同时给出了最大允许传输间隔以及一个实际例子。实践证明本文中给出的方法在简单的系统中是十分有效的。接着提出了一个减小网络诱导时延的算法,仿真结果表明了该方法的有效性。

To guarantee the globally exponentially stable of closed-loop system, delay must be bounded. In this paper, the model of Networked Control Systems with network-induced delay are discussed, and the maximum allowable transfer interval （MATI） is given through a theorem. The methods discussed here are proved to be practical through a simple example. Then an optimal algorithm which can minimize network-induced delay is proposed, simulation result proves the effectiveness of this algorithm.
