Consider the closed-loop system in Figure AP6.5. Suppose that all gains are positive, that is, K1Â > 0, K2Â > 0, K3Â > 0, K4Â > 0, and K5Â > 0.
(a) Determine the closed-loop transfer function T(s) = Y(s)/R(s).
(b) Obtain the conditions on selecting the gains K1, K2, K3, X4, and K5, so that the closed-loop system is guaranteed to be stable.
(c) Using the results of part (b), select values of the five gains so that the closed-loop system is stable, and plot the unit step response.
