Detailed Description

PrescribedController is a concrete Controller that specifies functions that prescribe the control values of its actuators as a function of time.

The control functions are specified in the ControlFunctions property. Use prescribeControlForActuator() to assign a control function to an actuator based on the name or path of the actuator. After connecting the controller to the model, the added control function will be placed at the correct index in the ControlFunctions property. If modifying the ControlFunctions property directly, the number and order of functions must match the number and order of actuators connected to the controller. However, it is recommended to use prescribeControlForActuator() to ensure the correct mapping between actuator and control function.

When loading from file, the order of the control functions in the file must match the order of actuators connected to the controller. If prescribeControlForActuator() is used to assign control functions, the control functions will be stored in the correct order in the ControlFunctions when saving the controller to file (since they are reordered as described above).

A controls storage file can be specified in the controls_file property. Each column must be either the name or path of an actuator in the model. If the actuator name is used as the column label, the first actuator with a matching name will be connected to the controller and assigned a control function based on the column data. Using actuator paths in the column labels is recommended to avoid ambiguity. Finally, any actuators with existing control functions will be ignored when setting controls from file.

Note: Prior to OpenSim 4.6, PrescribedController support setting a prescribed control based on the actuator's index in the ControlFunctions property. This interface is deprecated and will be removed in a future release.

Member Typedef Documentation

◆ Self

typedef PrescribedController OpenSim::PrescribedController::Self

This typedef might be useful within the member functions of this class.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ Super

typedef Controller OpenSim::PrescribedController::Super

Use this typedef to refer to the superclass of this class.

Avoid using the explicit type name of the superclass; this would introduce bugs if the superclass is changed.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

Constructor & Destructor Documentation

◆ PrescribedController() [1/2]

OpenSim::PrescribedController::PrescribedController ( )

Default constructor.

◆ PrescribedController() [2/2]

OpenSim::PrescribedController::PrescribedController	(	const std::string &	controlsFileName,
		int	interpMethodType = `1`
	)

Convenience constructor get controls from file.

Parameters

controlsFileName	string containing the controls storage (.sto)
interpMethodType	int 0-constant, 1-linear, 3-cubic, 5-quintic defaults to linear.

◆ ~PrescribedController()

OpenSim::PrescribedController::~PrescribedController ( )

override

Destructor.

Member Function Documentation

◆ assign()

void OpenSim::PrescribedController::assign ( Object & aObject )

inlineoverride

This allows copy assignment in the Java GUI.

Exceptions

Exception if the argument is not of type PrescribedController.

◆ clone()

PrescribedController* OpenSim::PrescribedController::clone ( ) const

inlineoverridevirtual

Create a new heap-allocated copy of the concrete object to which this Object refers.

It is up to the caller to delete the returned object when no longer needed. Every concrete object deriving from Object implements this pure virtual method automatically, via the declaration macro it invokes (e.g., OpenSim_DECLARE_CONCRETE_OBJECT()). Note that the concrete class overrides modify the return type to be a pointer to the concrete object; that still overrides the base class method because the return type is covariant with (that is, derives from) Object.

Implements OpenSim::Controller.

◆ computeControls()

void OpenSim::PrescribedController::computeControls	(	const SimTK::State &	s,
		SimTK::Vector &	controls
	)		const

overridevirtual

Compute the control values for all actuators under the control of this Controller.

Parameters

s	system state
controls	model controls

Implements OpenSim::Controller.

◆ extendConnectToModel()

void OpenSim::PrescribedController::extendConnectToModel ( Model & model )

overrideprotectedvirtual

Perform any necessary initializations required to connect the component into the Model, and check for error conditions.

extendConnectToModel() is invoked on all components to complete construction of a Model, prior to creating a Simbody System to represent it computationally. It may also be invoked at times just for its error-checking side effects.

If you override this method, be sure to invoke the base class method first, using code like this:

void MyComponent::extendConnectToModel(Model& model) {
    Super::extendConnectToModel(model); // invoke parent class method
    // ... your code goes here
}

Note that this method is expected to check for modeling errors and should throw an OpenSim::Exception if there is something wrong. For example, if your model component references another object by name, you should verify that it exists in the supplied Model, which is not guaranteed since components may be independently instantiated or constructed from XML files.

Parameters

[in,out] model The Model currently being constructed to which this ModelComponent should be connected.

Reimplemented from OpenSim::Controller.

◆ get_ControlFunctions()

const FunctionSet& OpenSim::PrescribedController::get_ControlFunctions ( ) const

inline

Get the value of the ControlFunctions property.

◆ get_controls_file()

const std::string& OpenSim::PrescribedController::get_controls_file ( ) const

inline

Get the value of the controls_file property.

◆ get_interpolation_method()

const int& OpenSim::PrescribedController::get_interpolation_method ( ) const

inline

Get the value of the interpolation_method property.

◆ getClassName()

static const std::string& OpenSim::PrescribedController::getClassName ( )

inlinestatic

This returns "PrescribedController".

See getConcreteClassName() if you want the class name of the underlying concrete object instead.

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ getConcreteClassName()

const std::string& OpenSim::PrescribedController::getConcreteClassName ( ) const

inlineoverridevirtual

Returns the class name of the concrete Object-derived class of the actual object referenced by this Object, as a string.

This is the string that is used as the tag for this concrete object in an XML file. Every concrete class derived from Object automatically overrides this method via the declaration macro it uses. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.

See also: getClassName()

Implements OpenSim::Controller.

◆ prescribeControlForActuator() [1/2]

void OpenSim::PrescribedController::prescribeControlForActuator	(	const std::string &	actuLabel,
		const Function &	prescribedFunction
	)

Assign a prescribed control function for the desired actuator identified by the provided label.

The label can be either the name of the actuator, or the absolute path to the actuator in the model.

Parameters

actuLabel	label for the actuator in the controller
prescribedFunction	the actuator's control function

Note: As of OpenSim 4.6, PrescribedController no longer takes ownership of the passed in Function and instead makes a copy.

◆ prescribeControlForActuator() [2/2]

void OpenSim::PrescribedController::prescribeControlForActuator	(	int	index,
		Function *	prescribedFunction
	)

inline

◆ safeDownCast()

static PrescribedController* OpenSim::PrescribedController::safeDownCast ( OpenSim::Object * obj )

inlinestatic

For use in MATLAB and Python to access the concrete class.

Example: cObj = PrescribedController.safeDownCast(obj). This is equivalent to dynamic_cast<PrescribedController*>(obj) in C++.

◆ set_ControlFunctions()

void OpenSim::PrescribedController::set_ControlFunctions ( const FunctionSet & value )

inline

Set the value of the ControlFunctions property.

◆ set_controls_file()

◆ updateFromXMLNode()

void OpenSim::PrescribedController::updateFromXMLNode	(	SimTK::Xml::Element &	objectElement,
		int	versionNumber
	)

overrideprotectedvirtual

Use this method to deserialize an object from a SimTK::Xml::Element.

The element is assumed to be in the format consistent with the passed-in versionNumber. If there is a file attribute in objectElement it will be ignored; if you want it processed you should call readObjectFromXMLNodeOrFile() instead.
