Detailed Description

MocoControlTrackingGoal

The squared difference between a control variable value and a reference control variable value, summed over the control variables for which a reference is provided, and integrated over the phase. This can be used to track actuator controls, muscle excitations, etc.

This goal is computed as follows:

\[ \int_{t_i}^{t_f} \sum_{c \in C} w_c \|x_{m,c}(t) - x_{e,c})\|^2 ~dt \]

We use the following notation:

\( t_i \): the initial time of this phase.
\( t_f \): the final time of this phase.
\( C \): the set of control variables being tracked.
\( w_c \): the weight for control \( c \).
\( x_{m,c}(t) \): control signal \( c \).
\( x_{e,c}(t) \): reference data for control signal \( c \).

This goal has two labeling modes: 'auto' and 'manual':

'auto': The column labels of the reference must exactly match the names of controls, and all controls with a matching column in the reference data are tracked. By default, all column labels for the reference data must match the name of a control. Setting allow_unused_references to false allows the reference to contain columns whose labels do not match a control; such columns are then ignored.
'manual': The association between controls and columns of the reference data is manually specified via the reference_labels property. Only the controls for which a reference label is specified are tracked. Enter this mode by providing reference labels through the reference_labels property or the setReferenceLabel() function. The allow_unused_references property does not apply in this mode.

Control variable names

Control variable names are based on paths to actuators, e.g., /forceset/soleus_r. For non-scalar actuators, the control variable name includes the index for the actuator control; e.g., /forceset/body_actuator_0, where 'body_actuator' is the name of the actuator and _0 specifies the control index.

Reference data

The reference can be provided as a file name to a STO or CSV file (or other file types for which there is a FileAdapter), or programmatically as a TimeSeriesTable.

Scale factors

Use addScaleFactor() to add a MocoParameter to the MocoProblem that will scale the tracking reference data associated with a control in the tracking cost. Scale factors for this goal can be useful if the magnitude of the tracking reference data is either unknown or unreliable (e.g., electromyography data). Scale factors are applied to the tracking error calculations based on the following equation:

error = modelValue - scaleFactor * referenceValue

In other words, scale factors are applied when computing the tracking error for each control, not to the reference data directly. Therefore, if a column in the reference data is tracked by two different controls, the scale factor will only scale the column for the associated control. The tracking error for the other control is unaffected.

Adding a scale factor to a MocoControlTrackingGoal.

auto* controlTrackingGoal = problem.addGoal<MocoControlTrackingGoal>();
...
controlTrackingGoal->addScaleFactor(
        'soleus_scale_factor', '/forceset/soleus_r', {0.01, 1.0});

Helpful tips

Tracking problems in direct collocation perform best when tracking smooth data, so it is recommended to filter the data in the reference you provide to the cost.

◆ addScaleFactor()

void OpenSim::MocoControlTrackingGoal::addScaleFactor	(	const std::string &	name,
		const std::string &	control,
		const MocoBounds &	bounds
	)

Add a MocoParameter to the problem that will scale the tracking reference data associated with the specified control.

Scale factors are applied to the tracking error calculations based on the following equation:

error = modelValue - scaleFactor * referenceValue

In other words, the scale factor is applied when computing the tracking error for each control, not to the reference data directly. Therefore, if a column in the reference data is tracked by two different controls, the scale factor will only scale the column for the associated control. The tracking error for the other control is unaffected.

Exception if the argument is not of type MocoControlTrackingGoal.

◆ calcGoalImpl()

You may need to realize the state to the stage required for your calculations.

Do NOT realize to a stage higher than the goal's stage dependency; doing so will cause an exception to be thrown. The Lagrange multipliers for kinematic constraints are not available.

◆ clearReferenceLabels()

void OpenSim::MocoControlTrackingGoal::clearReferenceLabels ( )

inline

Clear the 'reference_labels' property, which ensures this goal is used in 'auto' labeling mode.

◆ clone()

MocoControlTrackingGoal* OpenSim::MocoControlTrackingGoal::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::MocoGoal.

◆ getAllowUnusedReferences()

◆ getClassName()

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

This returns "MocoControlTrackingGoal".

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::MocoControlTrackingGoal::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.

const TableProcessor& OpenSim::MocoControlTrackingGoal::getReference ( ) const

inline

If no reference has been provided, this returns an empty processor.

◆ getReferenceLabel()

std::string OpenSim::MocoControlTrackingGoal::getReferenceLabel ( const std::string & control ) const

inline

◆ hasReferenceLabel()

bool OpenSim::MocoControlTrackingGoal::hasReferenceLabel ( const std::string & control ) const

inline

◆ initializeOnModelImpl()

void OpenSim::MocoControlTrackingGoal::initializeOnModelImpl ( const Model & ) const

overrideprotectedvirtual

Perform any caching before the problem is solved.

You must override this function and invoke setRequirements().

Precondition(s):: The model is initialized (initSystem()) and getModel() is available. The passed-in model is equivalent to getModel(). Use this opportunity to check for errors in user input.

Implements OpenSim::MocoGoal.

◆ printDescriptionImpl()

void OpenSim::MocoControlTrackingGoal::printDescriptionImpl ( ) const

overrideprotectedvirtual

Print a more detailed description unique to each goal.

Reimplemented from OpenSim::MocoGoal.

◆ safeDownCast()

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

inlinestatic

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

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

◆ setAllowUnusedReferences()

void OpenSim::MocoControlTrackingGoal::setAllowUnusedReferences ( bool tf )

inline

Specify whether the reference can have columns not associated with controls.

If set true, then such columns will be ignored by the cost. If false, such columns will cause an Exception to be raised. Only takes effect in 'auto' labeling mode.

◆ setReference()

void OpenSim::MocoControlTrackingGoal::setReference ( const TableProcessor & ref )

inline

Provide a table containing reference values for the controls you want to track.

In 'auto' labeling mode, each column label must be a control variable name. In 'manual' labeling mode, the column labels need not be control variable names; use setReferenceLabel() to associate controls with columns. The table is not loaded until the MocoProblem is initialized.

◆ setReferenceLabel()

void OpenSim::MocoControlTrackingGoal::setReferenceLabel	(	const std::string &	control,
		const std::string &	label
	)

inline

Set the column of the reference data that a given control should track.

Multiple controls can track the same column of the reference data. This replaces the reference label for the given control, if one had already been provided. If controls are not manually associated with a reference label, then it is assumed that the column labels for the reference data exactly match the names of controls.

◆ setWeightForControl()

void OpenSim::MocoControlTrackingGoal::setWeightForControl	(	const std::string &	controlName,
		const double &	weight
	)

inline

Set the weight for an individual control variable.

If a weight is already set for the requested control, then the provided weight replaces the previous weight. If no weight is specified for a control, a weight of 1.0 is used internally. Set the weight to 0 to avoid tracking a given control. An exception is thrown if a weight for an unknown control is provided.

◆ setWeightSet()

void OpenSim::MocoControlTrackingGoal::setWeightSet ( const MocoWeightSet & weightSet )

inline

Provide a MocoWeightSet to weight the control variables in the cost.

Replaces the weight set if it already exists.
