02. Draw the polar plot of 6 1 a) G(s) s(s+1) b) G(S) = (s+1)(s+2)(s+3) Q3. Sketch the Nyquist plot for unity feedback control systems having a) G(s) = 10(s+4) s(S-2) 6(S+2) b) G(S) = S(S+1)(s+2) and find out whether the systems are stable. Q4. A unity feedback control systems has the following loop transfer functions k G(s) s(s + 1)(s + 2) Determine Kcand We. It is desired that the maximum overshoot Mp of the control system should be 16.25%, damping ratio 0.52. Determine design gain Kd and then gain margin
