Extracted text: 3) A plant with the given transfer functoin Gp(s) is going to be controlled by a P-controller of gain K by using unity feedback. If the system subjected to a unit ramp input: 1. Gp(s) : s(0.02s + 1) a. What should be the proportional gain K in order to have a non-oscillatory closed loop response with steady state error less than 0.1. b. Find the stability margin "a" of the closed loop system when K=12 .
