% Use MATLAB, the Control System Toolbox, and the
% following statements to solve Skill-Assessment
% Exercise 11.2.
% When the SISO Design for SISO Design Task Window appears:
% 1. Right-click on the Bode plot area and select Grid.
% 2. Note the phase margin shown in the MATLAB Command Window.
% 3. Using the Bode phase plot, estimate the frequency at
% which the phase margin from Step 2 occurs.
% 4. On the SISO Design for SISO Design Task Window toolbar,
% click on the red zero.
% 5. Place the zero of the compensator by clicking on the
% gain plot at a frequency that is 1/10 that found in Step 3.
% 6. On the SISO Design for SISO Design Task Window toolbar,
% click on the red pole.
% 7. Place the pole of the compensator by clicking on the gain
% plot to the left of the compensator zero.
% 8. Grab the pole with the mouse and move it until the phase
% plot shows a P.M. equal to that found in Step 2.
% 9. Right-click in the Bode plot area and select
% Edit Compensator. . .
%10. Read the lag compensator in the Control and Estimation
% Tools Manager Window.
