Question
Transcribed Image Text:6. Consider the feedback system shown in Figure 5. The process transfer
function is marginally stable, The controller is the proportional-derivative
(PD) controller
G,(s) = K, +Kps.
Determine if it is possible to find values of K, and K, 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 e, = lim e(t) <0.1 and the damping of the closed-loop
system is 5=V2/2.
