Question:

A control system has the following transfer functions in its block diagram (see Fig. 11.8): G_c=1, G_v= 2, G_d= G_p= 2 / s(s + 4), G_m= 1. For a unit step change in Y_sp, determine

(a) Y(s) / Y_sp(s)
(b) y(ˆž)
(c) Offset (note proportional control is being used)
(d) y(0.5)
(e) if the closed-loop response is oscillatory
