Chapter 0, Problem DP6.8(choose chapter or problem)
Consider the feedback system shown in Figure DP6.8.The process transfer function is marginally stable. The controller is the proportional-derivative (PD) controller Gc(s) = KP + KDs. Determine if it is possible to find values of Kp and KD such that the closed-loop system is stable. If so, obtain values of the controller parameters such that the steady-state tracking error E(s) = R(s) - Y(s) to a unit step input R(s) = 1/s is ess = lim e{t) ^ 0.1 and the damping of the closedloop system is = V2/2.
