functioninitialResponse

Initial condition response plot of a discrete zeros-and-poles transfer function

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

Syntax

DiscreteZerosAndPoles.Plot.initialResponse(zp)

Description

This function plots the initial response, i.e. the zeros input response of a zeros and poles transfer function. It is based on timeResponse.

Example

  DiscreteZerosAndPoles q = Modelica_LinearSystems2.DiscreteZerosAndPoles.q();
  Modelica_LinearSystems2.DiscreteZerosAndPoles dzp=(q^2 - 1.5*q + 0.6)/( (q - 0.8)*(q - 0.75) )
  Real y0=1;
  dzp.Ts = 0.02;

  Modelica_LinearSystems2.DiscreteZerosAndPoles.Plot.initialResponseZP(dzp, y0=y0, tSpan=1)
  // gives:
