Solution Summary

This solution provides step by step equations for calculating phase margin using a system formula.

Solution Preview

The general method is this:
First we find the put s=jw in the system:

G(jw)=6.14(1+jw/5)/((jw(1+jw/2)(1+jw/10))

Then we find w such that |G(jw)|=1. After finding such an w, we find the phase of G(jw) for that w and call it phi. "Phase ...
