% Use MATLAB, the Control System Toolbox, and the following statements to
% solve Skill-Assessment Exercise 11.3.
% 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 and bandwidth shown in the MATLAB
% Command Window.
% 3. On the SISO Design for SISO Design Task Window toolbar,
% click on the red pole.
% 4. Place the pole of the compensator by click- ing on the
% gain plot at a frequency that is to the right of the
% desired bandwidth found in Step 2.
% 5. On the SISO Design for SISO Design Task Window toolbar,
% click on the red zero.
% 6. Place the zero of the compensator by click- ing on the
% gain plot to the left of the desired bandwidth.
% 7. Reshape the Bode plots: alternately grab the pole and the
% zero with the mouse and alternately move them along the
% phase plot until the phase plot show a P.M. equal to that
% found in Step 2 and a phase-margin frequency close to the
% bandwidth found in Step 2.
% 8. Right-click in the Bode plot area and select Edit Compensator . . .
% 9. Read the lead compen- sator in the Control and Estimation Tools
% Manager Window.
