Effect of Phase Lead Compensator on Phase and Gain margins

[AnkleBreaker]

Homework Statement

I was just wondering what was the general effect on phase and gain margins when a phase lead compensator was is added to a system.

Phase lead compensators shift Bode phase plots upward in a desired frequency range. This increases phase margin, which improves damping.
