Homework Statement
Find the Bode Plot, and the phase and gain margins for the uncompensated system.
Homework Equations
G = (3.6s+6)/(s(.1s^2+.7s+1))
The Attempt at a Solution
I understand the phase and gain margin ideas, but the gain margin hinges on the phase crossing -180 degrees, and in this case it never crosses. So am I doing something wrong here? If not, how do I find the gain margin in this case? Is it infinite? Thanks for any help.
