A control system with negative unity feedback has a process

and we wish to use proportional plus integral compensation, where

the steady-state error of this system for a ramp input is zero, (a) Set K/ = 1 and find a suitable value of KP so the step response will have an overshoot of approximately 20%. (b) What is the expected settling time (with a 2% criterion) of the compensated system?
