The set-point of the control system under proportional control (Kc= 5) undergoes a step change of magnitude 2. For G,G, 2 and G = 1, (s + 1)(2s + 1) (a) Determine when the maximum value of y occurs. (b) Determine the offset. (c) Determine the period of oscillation. (d) Sketch y(t) as a function of time, showing key character is tics as determined in (a), (b), and (c).
