Prelab 1. a. Given the transfer function G s 25 s2 4s 25 , evaluate the percent overshoot, settling time, peak time, and rise time. Also, plot the poles. b. Add a pole at 200 to the system of Prelab 1a. Estimate whether the transient response in Prelab 1a will be appreciably affected. c. Repeat Prelab 1b with the pole successively placed at 20;
