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
Real[:]	f		Frequency vector (either in Hz or rad/s)
Real[size(f, 1)]	a		Absolute value/magnitude vector (either without unit or in dB)
Modelica.Units.NonSI.Angle_deg[size(f, 1)]	phi		Angles in degree
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
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))
Plot.Records.Diagram	diagram		Diagram layout
Plot.Records.Device	device	Plot.Records.Device()	Properties of device where figure is shown
