NicholsGridLines

NicholsGridLines

is an option to NicholsPlot that specifies contours of constant magnitude and constant phase of the closed-loop system.

Details

  • The following settings can be given:
  • Noneno contours drawn
    Automaticcontours chosen automatically
    {magnitude,phase}contours specified by magnitude and phase are drawn
  • The magnitude values are the absolute values.
  • The phase values are in radians.
  • The following settings can be given for magnitude and phase:
  • Noneno contours drawn
    Automaticcontours chosen automatically
    {c1,c2,}draw the contours ci
    {{c1,style1,r1},}contours with specified styles and regions
  • The default style of a magnitude contour is Dashed, and the default style of a phase contour is Dotted.
  • The setting ri specifies that a point should be included if ri[x,y,ci] yields True.
  • The default value of ri is Automatic.
