Simulation scenario description

expand all in page

Syntax

sim_obj = sdo.SimulationTest(modelname)

Description

Create a scenario to simulate a Simulink^®model. A simulation scenario specifies input signals, model parameter and initial state values, and signals to log for a model. You can also specify linear systems to compute if you haveSimulink Control Design™toolbox. Use a simulation scenario to simulate a model with alternative inputs and model parameter and initial state values, without modifying the model.

Construction

sim_obj= sdo.SimulationTest(modelname)constructs ansdo.SimulationTestobject and assigns the specified model name to theModelNameproperty and default values to the remaining properties.

You can also construct ansdo.SimulationTestobject using thecreateSimulatormethod of ansdo.Experimentobject. ThecreateSimulatormethod configures the properties of thesdo.SimulationTestobject to simulate the model associated with the experiment.

Input Arguments

modelname

Simulink model name, specified as a character vector or string. For example,'sdoHydraulicCylinder'.

The model must be on the MATLAB^®path.

适当的ties

`InitialState`	Model initial state for simulation. This property can be any initial state format that`sim`command supports.
`Inputs`	Input signals. Specify signals to apply to root level input ports when simulating the model. The signal can be any input signal format that the`sim`command supports. Default:`[]`
`LoggedData`	Data logged during simulation. You must also specify the signals to log in the`LoggingInfo`property. The logged data is stored in a`Simulink.SimulationOutput`object and is populated by the`sim`method. This property is read-only. Default:`[]`
`LoggingInfo`	Signals to log when simulating a model. This property is a`Simulink.SimulationData.ModelLoggingInfo`object. Specify the signals to log in its`Signals`property. Default:`1x1 Simulink.SimulationData.ModelLoggingInfo`object
`SystemLoggingInfo`	Linear system logging settings. This property is a vector of`sdo.SystemLoggingInfo`objects. If you specify the`SystemLoggingInfo`property, the`sim`method linearizes the model during simulation. Note You can also use`linearize`(Simulink Control Design)command fromSimulink Control Designto compute linear systems. However, to use fast restart, you must use`SystemLoggingInfo`property and`sim`instead. Default:`[]`
`ModelName`	金宝app与模拟仿真软件模型的名字scenario. The model must be on the MATLAB path.
`Name`	Name of the scenario Default:`''`
`Parameters`	Parameter values. The software changes the model parameters to the specified values before simulating the model and restores them to their original value after the simulation completes. This property must be a`param.Continuous`object. Default:`[]`

Methods

fastRestart	Simulate金宝appmodel in fast restart mode using simulation scenario
find	Find logged data set
prepareToDeploy	Configure simulation scenario for deployment with金宝appCompiler
sim	Simulate金宝appmodel using simulation scenario
who	List logged data names

Create Simulation Scenario for Model

Open Live Script

Create a simulation scenario for a model.

Pressures = Simulink.SimulationData.SignalLoggingInfo; Pressures.BlockPath ='sdoHydraulicCylinder/Cylinder Assembly'; Pressures.OutputPortIndex = 1; simulator = sdo.SimulationTest('sdoHydraulicCylinder');

Specify model signals to log.

simulator.LoggingInfo.Signals = [Pressures];

Create Simulation Scenario for Experiment

Open Live Script

Specify an experiment for a model.

experiment = sdo.Experiment('sdoRCCircuit');

Create a simulation scenario for the experiment.

sim_obj = createSimulator(experiment);
