Question

5.1) A speed-control system of an electric motor has the blockdiagram given in Figure P.5.1. The input signal is a voltage andrepresents the desired speed. (A) The gain of the tachometer is Hk = 0.02. What arethe units on this gain? (B) If the desired motor speed is 300 rpm, find the (constant)input voltage, r(t), that should be applied. (C) It is desired that the motor speed increase linearly (as aramp) from 0 rpm to 500 rpm in 20s. The desired speed is then tostep back to 200 rpm and remain at that speed. Sketch the requiredinput signal r(t), in volts. (D) Give the block diagram of the unity feedback model for thissystem, such that both the input and output have the units ofrpm.
