SystemModelValidationData

SystemModelValidationData[…]

represents the symbolic requirement validation results obtained from SystemModelValidate.

Details

  • SystemModelValidationData is generated by the function SystemModelValidate and provides ways of summarizing, exploring and extracting system model requirement validation results.
  • A SystemModelValidationData[…] object val can be used to retrieve properties through val["property"].
  • val["Properties"] gives a list of available properties.
  • Typical properties include:
  • "Configuration"failure configurations to report
    "FailureIntervals"intervals of time at which the requirement fails
    "FailureIntervalsPlot"plot of failure intervals
    "FailurePlot"plot of validation
    "FirstFailureTime"first time at which the requirement fails
    "SuccessProbability"validation success probability
  • Other specifications include:
  • {p1,…,pn}get the values of properties pi
    "Summary"get the summary of the validation

Basic Examples  (1)

Validate a requirement for the output of a TransferFunctionModel:

Wolfram Language code: req = SystemModelEventually[t, 1.6 ≤ Subscript[, 1][t]];

Specify a parameter uncertainty on a, an input function and a number of simulations:

Wolfram Language code: spec = <|"ParameterValues" -> {a -> NormalDistribution[1, 0.1]}, "Inputs" -> {1 -> UnitStep}, "SimulationCount" -> 50|>;

Validate the requirement producing SystemModelValidationData:

Wolfram Language code: val = SystemModelValidate[TransferFunctionModel[{{{2*(1 - a*s)}}, 2*(1 + s/2 + s^2)}, s], req, spec]

Extract properties from the object:

Wolfram Language code: val["FailureIntervals"]

Scope  (1)

Properties  (1)

Validate a requirement in a model of a circuit when the resistance is in an interval using 50 simulations:

Wolfram Language code: spec = <|"ParameterValues" -> {"R2.R" -> Quantity[Interval[{1/10, 1}], "Ohms"]}, "SimulationCount" -> 50|>;
Wolfram Language code: req = SystemModelAlways[t, "R2.p.v"[t] < 0.55];
Wolfram Language code: val = SystemModelValidate[[image], req, spec]

Find the list of available properties:

Wolfram Language code: val["Properties"]

Extract the success probability:

Wolfram Language code: val["SuccessProbability"]

Extract the failure count and the result for the validation success:

Wolfram Language code: val[{"FailureCount", "ValidationSucceeded"}]

Extract the stored failure configurations:

Wolfram Language code: val["Configuration"]

Extract the stored failure intervals for the first stored configuration:

Wolfram Language code: val["FailureIntervals", 1]

Extract the failure intervals plot for the first stored configuration:

Wolfram Language code: val["FailureIntervalsPlot", 1]

Extract the failure plot for the first stored configuration:

Wolfram Language code: val["FailurePlot", 1]

Extract the summary:

Wolfram Language code: val["Summary"]

Applications  (1)

Validate the requirement, "Whenever the controller is turned on, the room temperature must have a value between 18.5 °C and 21.0 °C." in a model for room heating:

Wolfram Language code: model = [image];
Wolfram Language code: req = SystemModelAlways[t, "thermostat.onOffController.y"[t]18.5 < "temperatureSensor1.T"[t] < 21.0];

Validate a simulation interval for several possible values of the resistance in the heating circuit setting:

Wolfram Language code: spec = <|"SimulationInterval" -> 2000, "ParameterValues" -> {"room.radiator.heatingCircuit.R" -> {0.1, 1, 10, 100, 1000}}|>;
Wolfram Language code: val = SystemModelValidate[model, req, spec]

Extract the stored failure configurations:

Wolfram Language code: fail = val["Configuration"]

Extract the failure plot for the first stored configuration:

Wolfram Language code: val["FailurePlot", 1]

Simulate and plot the state of the controller in the failure configuration:

Wolfram Language code: sim = SystemModelSimulate[model, 2000, fail[[1]]]
Wolfram Language code: SystemModelPlot[sim, {"thermostat.onOffController.y"}]

Despite the fact that the controller is always on, the room temperature drops below the minimum in the failure configuration:

Wolfram Language code: SystemModelPlot[sim, {"temperatureSensor1.T", 18.5, 21.0}, PlotRange -> All]
