Phase margin (deg) >

Phase margin, specified in degrees.

By default, negative feedback, specified in Feedback sign on page 16-129, is used to

compute the phase margin.

You can specify only one phase margin bound on the linear system in this block.

Settings

Default:

[] for Gain and Phase Margin Plot block.

30 for Check Gain and Phase Margins block.

Positive finite number.

Tips

• To assert that the phase 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 phase margin from the plot window, right-click the plot, and select
  Bounds > Edit Bound. Specify the new phase margin in Phase margin >. You must
  click Update Block before simulating the model.

Command-Line Information

Parameter: PhaseMargin

Type: character vector

Value: [] | 30 | positive finite number. Must be specified inside single quotes ('').

Default: '[]' for Gain and Phase Margin Plot block, '30' for Check Gain and Phase

Margins block.
