Question:

A closed-loop transfer function is

(a) Determine the steady-state error for a unit step input R(s) = 1/s.
(b) Assume that the complex poles dominate, and determine the overshoot and settling time to within 2% of the final value.
(c) Plot the actual system response, and compare it with the estimates of part (b).
