4 - Some Common Loose Ends
Published online by Cambridge University Press: 09 April 2021
Summary
The Nyquist stability criterion ushers the advanced student into a truly deep understanding of feedback theory. To master this concept, a student needs two tools from the mathematics of complex analysis: conformal mapping and Cauchy's principle of the argument. In keeping with the goal of making this guide completely self-contained, a few pages of Chapter 4 are devoted to these topics.Afterward, we dive fully into theNyquist criterion and show how it relates to phase margin. A few examples of Nyquist plots (using Bode plots as a guide) are also given in this chapter.
