functionstep
Step response plot
Extends from Modelica_LinearSystems2.Internal.PartialPlotFunction (Interface of a plot function).
Information
Syntax
ZerosAndPoles.Plot.step(zp) or ZerosAndPoles.Plot.step( zp, dt, tSpan, x0, columnLabels, defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramTimeResponse(), device=Modelica_LinearSystems2.Utilities.Plot.Records.Device())
Description
This function plots the step response of a zeros-and-poles transfer function. It is based on timeResponse.
Example
ZerosAndPoles p = Modelica_LinearSystems2.ZerosAndPoles.p(); Modelica_LinearSystems2.ZerosAndPoles zp =(p + 1)/(p^2 + 5*p + 12); algorithm Modelica_LinearSystems2.ZerosAndPoles.Plot.step(zp, dt=0.02, tSpan=3) // gives:
