Answer 1

H(S) = 50(S + 2)/S(S + 5) theta_0/theta_d = 20/S + 10/1 + 50(S + 2)/S(S + 5) = 20S(S + 5)/S(S + 5) + 50(S + 2) = CLTF OLTF = 20(S) (S + 5)/S^2 + 5S + 50S + 100 - 200^2 - 100S = 20(S) (S + 5)/-19S^2 - 45S + 100 type 'U' K_p Lt^s rightarrow 0 G(S) = Lt_S rightarrow 0 20(S) (S + 5)/-19S^2 - 45S + 100 = 0 Steady state error = 1/1 + K_p = 1/1 + 0 = 1
