Chapter 10, Problem 10.25P
Consider the PI speed control system shown in Figure 10.6.2, where I = c = 2. The desired time constant is x = 0.1. (a) Compute the required values of the gains for the following three sets of root locations.
- 5 = —10, —15 (root separation factor is 1.5)
- 5 = —10, —20 (root separation factor is 2)
- j = —10, —50 (root separation factor is 5)
(b) Use a computer method to plot the response of the speed co (J) for a unit-step command for each of the cases in part (a). Discuss the effects of the root separation factor on the rise time, the overshoot, and the maximum required torque.
