Question: The closed-loop transfer function of a unity-feedback control MEMS is GCL(s) = 2500/s2 + 40s + 2500
(a) What changes are needed in the damping ratio p and natural frequency ~n to produce a reduction of 20% in the maximum overshoot and a reduction of 15% in the rise time under unit step input?
(b) How will the closed-loop poles move in the complex plane as a result of these changes?
