Question 3. The system shown below is a more complex version of the cruise control system covered in class 2 where the car transfer function is Gp = s2+10s+100 and the controller transfer function is Gc = Ki S Determine the value K; such that the steady state error for a ramp reference input is minimal while traveling on a constant grade road without causing any instability. (Hint: Start by manipulating the block diagram such that it becomes a subtraction block followed by a feedback loop) W(s) 5 R(s) GC C(s) Speed
