Consider a system shown in the figure below (feedback control
system in the presence of disturbance). (a) When D(s)=K
(proportional controller), find the transfer function
GW(s)=Y(s)/W(s) (b) Find the steady state output for the unit step
disturbance (let, w(t)=1) (c) Design a PI controller such that the
steady state output for the unit step disturbance is zero
