Information

Syntax

DiscreteStateSpace.Plot.initialResponse(ss);
   or
DiscreteStateSpace.Plot.initialResponse(
  dss,
  tSpan,
  x0,
  defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramTimeResponse(),
  device=Modelica_LinearSystems2.Utilities.Plot.Records.Device())

Description

This function plots the initial responses of a discrete state space system for the initial state vector x0 for each system corresponding to the transition matrix. It is based on timeResponse.

Example

  Modelica_LinearSystems2.StateSpace ss=Modelica_LinearSystems2.StateSpace(
    A=[-1.0,0.0,0.0; 0.0,-2.0,3.0; 0.0,-2.0,-3.0],
    B=[1.0; 1.0; 0.0],
    C=[0.0,1.0,1.0],
    D=[0.0])

  Real x0={1,0.5,0.5};

  Real Ts = 0.1;
  Modelica_LinearSystems2.Types.Method method=Modelica_LinearSystems2.Types.Method.StepExact;
  DiscreteStateSpace dss=DiscreteStateSpace(dss,Ts,method);

algorithm
  Modelica_LinearSystems2.DiscreteStateSpace.Plot.initial(dss, x0=x0)
