2. (40 pts) A unity feedback system is shown in Figure 2 w(s) + E(s), + Da(s) R(s) + Y(s) G(s) Figure 2 A unity feedback system with G(s) = 1 s(s + 4) Da(s) = K = = a) (20 pts) Given that the disturbance W(s) = 0, find the transfer function from R(s) to Y(s), and determine the value of K such that the overshot of the step response is 10% (Hint: the damping ratio / = 0.6) b) (20 pts) Given that the reference R(s) = 0 and K = 0, find the transfer function from W(s) to Y(s), and the steady-state error to a step disturbance W(s) 1 = S
