Consider the closed-loop system shown in Figure P11.6, where the transfer function of the process is that of a second-order system, i.e. k Ts +25TS +1 G,(s)= Y sp(s) E(s) U(s) Y(s) Ge(s) Gp(s) Figure P11.6 If the controller is a P controller (G(s)=k) (a) determine the closed-loop transfer function (b) determine the offset to a unit step change of the set point.
