奈氏曲线的单向环及其应用

One direction loop of Nyquist curve and its application

提出了改善闭环系统动态响应的方法 ,应用单向环的概念 ,提出了一种计算N值的简易方法 ,尤其对高阶系统 ,优点十分突出 ,从而使奈奎斯特判据判别控制系统稳定性时更加简单、可行 .

The paper puts forward one kind of sim ple method of calculating the value of N by applying the conception of the one direction loop,especially,to the system with high order,whose advantage is quite obvious.Thus,it makes disting uishing controlling system's stability more simply and feasibl y by using the Nyquist criterion.
