Options Page
The Options page contains settings for adding a grid and changing the plot's aspect ratio. This figure shows the Options page.
Check Show grid to display a grid on the root locus. If you have damping ratio constraints on your root locus, selecting Display damping ratios as % peak overshoot displays the damping ratio values along the grid lines. This figure shows both options activated for an imported model, Gservo
. If you want to verify these settings, type
at the MATLAB prompt and import Gservo
from the workspace into your SISO Design Tool.
Displaying Damping Ratio Values
The numbers displayed on the root locus gridlines are the damping ratios as a percentage of the overshoot values.
If you check the Equal box in the Aspect Ratio panel, the x and y-axes are set to equal limit values.
