Description

This function plots the time response of a discrete state space system. The character of the time response if defined by the input response, i.e. Impulse, Step, Ramp, or Initial.

Example

  import Modelica_LinearSystems2.DiscreteStateSpace;

  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 Ts = 0.1;
  Modelica_LinearSystems2.Types.Method method=Modelica_LinearSystems2.Types.Method.StepExact;
  DiscreteStateSpace dss=DiscreteStateSpace(ss,Ts,method);
  Types.TimeResponse response=Modelica_LinearSystems2.Types.TimeResponse.Step;

algorithm
  DiscreteStateSpace.Plot.timeResponse(dss, response=response);
