边界对应原理及其在稳定判断中对一类幅相特性的鉴别
The Boundary Correspondence Principle and it's Judgment of an Open-Loop Amplitude-Phase Characteritics in the Stable Assessment
-
摘要: 由环线理论简单地得到了边界对应原理,并进行了拓广.利用它对一类开环幅相特性的明显错误可作出鉴别.Abstract: The boundary correspondence principle can be obtained plainly by the loop-line theory and is also extended. And the evident errors of an open-loop amplitude-phase characteristic curve can be found by exploiting it.
