Simulink Control Design™ - MathWorks

Settings


Default:
[] for Bode Plot block
[10 100] for Check Bode Characteristics block


Must be specified as start and end frequencies:



  • Positive finite numbers for a single bound with one edge

  • Matrix of positive finite numbers for a single bound with multiple edges


For example, type [0.1 1;1 10] for two edges at frequencies [0.1 1] and [1 10].


  • Cell array of matrices with positive finite numbers for multiple bounds


Tips



  • To assert that magnitudes that correspond to the frequencies are satisfied, select both
    Include upper magnitude bound in assertion on page 16-21 and Enable
    assertion on page 16-32.

  • You can add or modify frequencies from the plot window:

    • To add new frequencies, right-click the plot, and select Bounds > New Bound.
      Select Upper gain limit in Design requirement type, and specify the
      frequencies in the Frequency column. Specify the corresponding magnitudes in
      the Magnitude column.

    • To modify the frequencies, drag the bound segment. Alternatively, right-click the
      segment, and select Bounds > Edit Bound. Specify the new frequencies in the
      Frequency column.




You must click Update Block before simulating the model.
