Question 4: Consider the following system: 0.01 a) Describe the response to a unit step input for K 0.01 and K-0.1 and determine the value of K for a non-oscillatory minimum response time. b) If we let K-1, what will be the value of the steady state error of this system in response to a unit step input? c) If we now replace the “proportional controller” (the box with the K in it) with a proportional integral (PI) controller, with a transfer function of 1+1/s, what will be the steady state error? d) If we now use a proportional derivative controller, with a transfer function of l+s, what will be the steady state error?
