ECE 3085 Homework 6 Due November 6, 2003 1. A motor has the following transfer function. ) 1 . 0 )( 01 . 0 ( 1 . 0 ) ( + + = s s s G p The closed-loop system should have a time constant sec 4 τ and a damping ratio δ = 0.707. a) Determine the value of K for a proportional compensator that will satisfy the damping ratio criterion. Plot the unit step response of the closed loop system using Matlab. b) Design a compensator that will meet all the specifications. c) Plot the resulting closed loop step response for the controller designed in part b), and compare your results to those obtained in part a) 2. For the motor described in Problem 1, a) Design a controller that has dominant poles at j 5 . 0 5 . 0 ± and zero steady-state

Then, plot the actual Bode plot using Matlab. On each Matlab plot, mark the corner frequencies, and the high and the low frequency asymptotes for both the magnitude and the angle plots. a) ) 1 . )( 01 . ( 1 . ) ( + + = s s s p G b) ) 1 . )( 01 .
