Problem 3 (10%) Consider an unstable plant with PI controller depicted in Fig. 4, where Kp , KI , a and input signal r are all constants.
One wants to design the PI controller and feedback gain c to stabilize the overall controlled system and to meet the following requirements:
(i) The controlled system has to be asymptotically stable.
(ii) Settling time 
are dampin ratio and natural frequency of a second order system respectively.
(iii) Damping ratio
