時延網(wǎng)絡(luò)控制系統(tǒng)的穩(wěn)定性分析

為保證閉環(huán)系統(tǒng)的全局漸進穩(wěn)定性，系統(tǒng)的時延必須是有界的。本文中討論了具有網(wǎng)
絡(luò)誘導時延的網(wǎng)絡(luò)控制系統(tǒng)的模型，同時給出了最大允許傳輸間隔以及一個實際例子。實踐證明本文中給出的方法在簡單的系統(tǒng)中是十分有效的。接著提出了一個減小網(wǎng)絡(luò)誘導時延的算法，仿真結(jié)果表明了該方法的有效性。

Abstract: 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.
