本文利用频率响应的结果来概述有时滞线性控制系统的乃魁斯特稳定性判据。研究了当其在正向回路、反馈回路或者两者之中都存在时滞时开环放大倍数和时滞的变化。现用一个简单的控制系统的稳定情况去说明这一方法。
In this paper, the results of frequency response are used to summarize the Nyquist stability criterion for a time-delay linear control system. The change of open-loop magnification and delay is studied when there is delay in the forward loop, feedback loop or both. Now use a simple control system to illustrate the stability of this method.
