Description

This function plots the bode-diagram of a transfer function.

Example

  ZerosAndPoles p = Modelica_LinearSystems2.ZerosAndPoles.p();
  Modelica_LinearSystems2.ZerosAndPoles zp =(p^2 + 5*p + 7)/(p + 2)/(p + 3);

Inputs

Type	Name	Default	Description
ZerosAndPoles	zp		ZerosAndPoles transfer function to be plotted
Integer	nPoints	200	Number of points
Boolean	autoRange	true	True, if abszissa range is automatically determined
SI.Frequency	f_min	0.1	Minimum frequency value, if autoRange = false
SI.Frequency	f_max	10	Maximum frequency value, if autoRange = false
Boolean	magnitude	true	= true, to plot magnitude
Boolean	phase	true	= true, to plot phase
Plot.Records.Diagram	defaultDiagram (from PartialPlotFunction)		Default diagram layout
Plot.Records.Device	device (from PartialPlotFunction)	Modelica_LinearSystems2.Utilities.Plot.Records.Device()	Properties of device where figure is shown
Boolean	Hz	true	= true, to plot abszissa in [Hz], otherwise in [rad/s] (= 2piHz)
Boolean	dB	false	= true, to plot magnitude in [], otherwise in [dB] (=20*log10(value))
Boolean	onFile	false	= true, if frequency response is stored on file as matrix [f,A,phi]
String	fileName	"frequencyResponse.mat"	If onFile=true, file on which the frequency response will be stored
String	matrixName	if Hz and not dB then "fHz_A_phiDeg" elseif Hz and dB then "fHz_AdB_phiDeg" elseif not Hz and dB then "f_AdB_phiDeg" else "f_A_phiDeg"	If onFile=true, Name of matrix on file
