ME360 Winter 2011 Tutorial #9 The transfer function for a plant is given as: ) 25 . 1 2 ( 1 ) ( 2 + = s s s s G p 1. Draw the block diagram for the system where the feedback compensation transfer function is given as: s T s H d + = 1 ) ( 2. What is the closed loop transfer function for this system? 3. Generate the equation that would be used to plot the root locus for T d . You should plot the root locus using Matlab. 4. For what values of T d is the system stable? 5. Design a controller that will make the system stable. You don’t have to find the gains (yet), but prove that this controller will work.

Plot the root locus using Matlab. What is the critical value for T d ? 8. Find the value for T d for the controller from 7 such that the oscillatory component of the response behaves as a system with a damping ratio of 0.8. 9. Find the gains to your controller and T d such that the system has a damping ratio of 0.9 and a natural frequency of 3.0 rad/s....
