StabilityMargins

StabilityMargins

is an option to frequency response plots such as BodePlot, NyquistPlot, and NicholsPlot that specifies the gain and phase margins to be shown on the plot.

Details

  • With StabilityMargins->True, the gain and phase margins are shown on the plot, and with StabilityMargins->False they are not shown.
  • StabilityMargins->{{fp,g},{fg,p}} shows the gain margin g at the phase crossover frequency fp and the phase margin p at the gain crossover frequency fg.
  • StabilityMargins->{{{fp 1,g1},{fp 2,g2},…},{{fg 1,p1},{fg 2,p2},…}} shows the margins at frequencies fpi and fgi.
  • The crossover frequencies are the units of the complex variable of the TransferFunctionModel in the plot, the gain margins are in absolute values, and the phase margins are in radians.
