Question 6 λω, A Proportional plus Integral (PI) controller is designed for the control of an underdamped second order plant of the form Gp(s) = s?+25wns+w Which of the following s-plane diagrams (with zeros and poles) relates to the closed loop transfer function of the plant with PI controller? Im(s) Im(s) Im(s) Im(s) x Rels) Rels) Re(s) Re(s) + х (a) (b) ) (c) (d) s-plane diagram (d) Os-plane diagram (a) s-plane diagram (b) s-plane diagram (c)
A Moving to another question will save this response. Question 8 What is the equivalent transfer function Y(S) U (S) of the following block diagram? K и H2 y H 1 OA Y(s) = U(S) H (K+H) 1+H H K+H OB. Y(S) U(S) I+H,H2 1 OC Y(s) U (S) 2 H. (1+KH,) 1+H H H/(1+H) -H 1+KH H, OD. Y(s) U(s) =
