FeedbackSector

FeedbackSector

is an option to NyquistPlot that specifies the sector limits of the nonlinearity in the feedback.

Details

  • FeedbackSector together with NyquistPlot can be used to analyze stability using the circle criterion.
  • FeedbackSector->{a,b} specifies a nonlinear feedback , where and is the input variable, is the output variable, and is the time variable.

Examples

Basic Examples  (1)

A stable system:

And its NyquistPlot lies within the circle for feedback in the sector {-4,50}:

Thus, the closed-loop system is stable for any feedback within sector {-4,50}:
