Unformatted text preview: of 0.707. (c) Compare the steady-state error to step inputs and the transient response characteristics of the uncompensated and compensated systems. Use Matlab to find the transient response characteristics. 3. A unity feedback control system has the following forward transfer function ) 3 )( 2 )( 1 ( ) ( + + + = s s s K s G Design a PID controller that will yield a peak time less than 1.57 sec and a damping ratio of 0.707, with zero error for step inputs. Plot the unit step response using Matlab. How close is it to the one predicted by the pair of dominant poles? If there is a significant difference, explain why....
