functionstep

Step response plot

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

Description

This function plots the step response of a transfer function. It is based on timeResponse.

Example

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

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