The open-loop transfer function of a DC motor is given as
ω(s) / Va(s) = 10 / (1 + 10s).
When connected in feedback as shown below, the approximate value of Ka that will reduce the time constant
of the closed-loop system by one hundred times as compared to that of the open-loop system is:
Correct :
