Question:

A closed-loop speed control system is subjected to a disturbance due to a load, as shown in Figure DP4.1. The desired speed is ωd(t) = 100 rad/s, and the load disturbance is a unit step input Td(s) = l/s. Assume that the speed has attained the no-load speed of 100 rad/s and is in steady state.
(a) Determine the steady-state effect of the load disturbance, and
(b) Plot ω(t) for the step disturbance for selected values of gain so that 10 ‰¤ K ‰¤ 25. Determine a suitable value for the gain K.
