Simulink Control Design™ - MathWorks

Off

Do not check that the gain and phase margins satisfy the specified values, during

simulation.

Tips

• Clearing this parameter disables the gain and phase margin bounds and the software
  stops checking that the gain and phase margins satisfy the bounds during simulation.
  The bounds are also greyed out on the plot.


• To only view the gain and phase margin on the plot, clear Enable assertion.

Command-Line Information

Parameter: EnableMargins

Type: character vector

Value: 'on' | 'off'

Default: 'off' for Nichols Plot block, 'on' for Check Nichols Characteristics block

Gain margin (dB) >

Gain margin, in decibels.

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

compute the gain margin.

Settings

Default:

[] for Nichols Plot block.

20 for Check Nichols Characteristics block.

• Positive finite number for one bound.


• Cell array of positive finite numbers for multiple bounds.
