About this document
Nyquist Stability Analysis Problems by colaarawr is a document available to read on EtoBox.
This document discusses determining phase and gain margins for two unity feedback control systems based on their open-loop transfer functions. For the first system with transfer function G(s)=K*s(s^2+s+4), the document asks to find the value of K for a 50 degree phase margin and then determine the corresponding gain margin. For the second system with transfer function (as+1)G(s)=2s, the document asks to find the value of a for a 45 degree phase margin.
