Basic Examples  (3)

Set the value of a parameter a in a model:

Wolfram Language code: model = CreateSystemModel[StateSpaceModel[{{{a, 0}, {0, b}}, {{1, 0}, {0, 1}}, {{1, 1}}, {{0, 0}}}, SamplingPeriod -> None, SystemsModelLabels -> None]];
Wolfram Language code: SetSystemModel[model, <|"ParameterValues" -> {"a" -> 10}|>];

The parameter value has changed in the model:

Wolfram Language code: model[{"ParameterValues", "a"}]

Rename a model by giving it a name:

Wolfram Language code: model = CreateSystemModel[StateSpaceModel[{{{a, 0}, {0, b}}, {{1, 0}, {0, 1}}, {{1, 1}}, {{0, 0}}}, SamplingPeriod -> None, SystemsModelLabels -> None]];
Wolfram Language code: SetSystemModel[model, <|"ModelName" -> "MyStateSpaceModel"|>];

The model now has the new name:

Wolfram Language code: model["ModelName"]

Enable external function evaluation in a model:

Wolfram Language code: model = Import["ExampleData/ModelWithExternalFunction.mo", "MO"]

Use SetSystemModel to trust external functions:

Wolfram Language code: SetSystemModel[model, <|"TrustExternalFunctions" -> True|>]

Simulate the model and plot the simulation results:

Wolfram Language code: SystemModelPlot["ModelWithExternalFunction.MyModel", "z", 10]

Properties & Relations  (1)

SystemModel generates a new model with applied changes:

Wolfram Language code: model = [image];
Wolfram Language code: model["ParameterValues"]
Wolfram Language code: model2 = SystemModel[model, {"a" -> 10}];
Wolfram Language code: {model["ParameterValues"], model2["ParameterValues"]}

SetSystemModel makes changes in place:

Wolfram Language code: SetSystemModel[model2, {"a" -> 14}];
Wolfram Language code: model2["ParameterValues"]
