摘要

众所周知,时间延迟,即使很短,也会导致一些反馈循环中的不稳定问题。当存在许多高频模式时,H(s,c)问题似乎是最糟糕的[例如1]在[2]中,对于单变量系统,小时间延迟对闭环系统稳定性的影响是通过观察图1高频率下的开环行为来确定的。本文处理一个相关的多变量问题,概述如下。设H(s,E)为奇摄动系统(1)的传递矩阵。

Multivariable Singularly-Perturbed Systems with Small Time Delays
It is well known that time delays, even + though very short, can cause instability + problems in some feedback loops. The H(s,c) problem seems to be worst when there are many high-frequency modes present [e.g. 1] In [2] the effect of small time delays on closed-loop system stability, for single variable systems, is determined by observing open-loop behavior at high Figure 1 frequency. This paper treats a related multivariable problem, outlined as follows. Let H(s,E) be the transfer matrix of the singularly-perturbed system (1).
