functionimpulse
Impulse response plot
Extends from Modelica_LinearSystems2.Internal.PartialPlotFunction (Interface of a plot function).
Information
Syntax
TransferFunction.Plot.impulse(tf) or TransferFunction.Plot.impulse( tf, dt, tSpan, x0, columnLabels, defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramTimeResponse(), device=Modelica_LinearSystems2.Utilities.Plot.Records.Device())
Description
This function plots the impulse 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.impulse(tf, dt=0.02, tSpan=3) // gives:
