Gain margin (dB) >
Gain margin, specified in decibels.
By default, negative feedback, specified in Feedback sign on page 16-129, is used to
compute the gain margin.
You can specify only one gain margin bound on the linear system in this block.
Settings
Default:
[] for Gain and Phase Margin Plot block.
20 for Check Gain and Phase Margins block.
Positive finite number.
Tips
- To assert that the gain margin is satisfied, select both Include gain and phase
margins in assertion on page 16-125 and Enable assertion on page 16-133. - To modify the gain margin from the plot window, right-click the plot, and select
Bounds > Edit Bound. Specify the new gain margin in Gain margin >. You must
click Update Block before simulating the model.
