A certain unity feedback system has the following
Chapter , Problem 12.12(choose chapter or problem)
A certain unity feedback system has the following open-loop system transfer function.
\(G(s) = \frac{5K}{s^3 + 6s^2 + 5s}\)
Obtain the Bode plots and compute the phase and gain margins for
a. K = 2
b. K = 20
c. Use the Bode plots to determine the upper limit on K for the system to be stable. Which is the limiting factor: the phase margin or the gain margin?
