Syntax

StateSpace.Plot.plotBodeSISO(ss)
   or
StateSpace.Plot.plotBodeSISO(ss, iu, iy, nPoints, autoRange, f_min, f_max, magnitude=true, phase=true, defaultDiagram=Modelica_LinearSystems2.Internal.DefaultDiagramBodePlot(), device=Modelica_LinearSystems2.Utilities.Plot.Records.Device() )

Description

Plots the bode-diagram of a transfer function.

Description

Function plotBodeSISO plots a bode-diagram of the transfer function corresponding to the behavior of the state space system from iu'th element of the input vector u to the iy'th element of the output vector y.

Example

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

  Integer iu=1;
  Integer iy=1;

algorithm
  Modelica_LinearSystems2.StateSpace.Plot.plotBodeSISO(ss, iu, iy)
