functiontimeResponse

Plot the time response of a system represented by a transfer function. The response type is selectable

Extends from Modelica_LinearSystems2.Internal.PartialPlotFunction (Interface of a plot function).

Information

Syntax

TransferFunction.Plot.timeResponse(tf);
   or
TransferFunction.Plot.timeResponse(
  tf,
  dt,
  tSpan,
  response,
  x0,
  defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramTimeResponse(),
  device=Modelica_LinearSystems2.Utilities.Plot.Records.Device())

Description

This function plots the time response of a transfer function. The character of the time response if defined by the input response, i.e. Impulse, Step, Ramp, or Initial.

Example

  TransferFunction s = Modelica_LinearSystems2.TransferFunction.s();
  Modelica_LinearSystems2.TransferFunction tf =(s + 1)/(s^2 + 5*s + 12);

  Types.TimeResponse response = Modelica_LinearSystems2.Utilities.Types.TimeResponse.Step;

algorithm
  Modelica_LinearSystems2.TransferFunction.Plot.timeResponse(tf, dt=0.02, tSpan=3, response=response)
//  gives:
