Answer 1

GH(s) = K(s + 3)/s(s - 3) poles = 0, zeros = -3 (1) No of asymptotes = p - z = 2 - 1 = 1 theta_A = (2q + 1)180/p - z Vertical-bar _q = 0 = 180^0 implies RL - diagram Centroid sigma poles - sigma zeros/p - z = 3 - 3/1 = 0 Break point: 1 + k(s + 3)/s - 3 = 0 implies dk/ds = 0 BP implies 1(s^2 - 3s) - (s + 3)(2s - 3) = 0 s^2 - 3s - 2s^2 - 6s + 3s + 9 = 0 - s^2 - 6s + 9 = 0 implies s = 1.24, - 7.24(valid) This is RL diagram for C(s)/R(s) (c based TF)
