Question: A closed-loop system has the following transfer functions: Gc = Kc(1 + 1 5s), Gv = 1, Gm = 1 s+ 1, Gp = 10s+

A closed-loop system has the following transfer functions: Gc = Kc(1 + 1 5s), Gv = 1, Gm = 1 s+ 1, Gp = 10s+ 1 (a) Use Bode stability criterion to determine the range of Kc that makes the closed-loop system stable (assuming Kc >0). (b) If Kc = 0.2, what is the phase margin? (c) What value of Kc will result in a gain margin of 1.7
