Question: The unity feedback system shown in Figure P8.3, where is to be designed for minimum damping ratio. Find the following: a. The value of K

The unity feedback system shown in Figure P8.3, where

K(s+ 2)(s+ 3) G(s) = s(s + 1)

is to be designed for minimum damping ratio. Find the following:

a. The value of K that will yield minimum damping ratio

b. The estimated percent overshoot for that case

c. The estimated settling time and peak time for that case

d. The justification of a second-order approximation (discuss)

e. The expected steady-state error for a unit ramp input for the case of minimum damping ratio

K(s+ 2)(s+ 3) G(s) = s(s + 1)
