.Modelica_LinearSystems2.WorkInProgress.RootLocusOld.rootLocus

Information

Syntax

Plot.rootLocus(modelName, t_linearize, modelParam, simulationSetup, diagram)

Description

This function examines a root locus analysis of a selected Modelica model over variation of a certain system parameter. Note, only first parameter modelParam[1] is considered for the analysis. The parameter is varied equidistantly from minimum to maximum value.

Example

Calling the function

Utilities.Plot.rootLocus(
  modelName = "Modelica.Mechanics.Rotational.Examples.First",
  t_linearize = 0,
  modelParam={
    Modelica_LinearSystems2.Records.ParameterVariation(
      Name="Jload",
      Min=1,
      Max=6,
      nVar=10,
      Unit="kg.m2")});

yields following diagram
