Detailed Description

This class represents a Probe which is designed to query a Vector of model values given system state.

This model quantity is specified as a SimTK::Vector by the pure virtual method computeProbeInputs(), which must be specified for each child Probe. In addition, the Probe model component interface allows operations to be performed on this value (specified by the property: probe_operation), and then have this result scaled (by the scalar property: 'scale_factor').

The data flow of the Probe is shown below:

|----------------------------------------------------------------------|

The model query is performed at Stage::Report, so that model values are up to date and is based on the specific Probe's overridden method computeProbeInputs(s). The final output of the probe is available by accessing getProbeOutputs(s). Note that all queries, operations, and scaling are performed by SimTK::Measures. Note also that to define a new child Probe class, three methods which are declared as pure virtual in this Probe abstract class need to be overridden:

computeProbeInputs() — returns the input probe values (i.e., model queries).
getNumProbeInputs() — returns the size of the vector of input probe values (i.e., model queries).
getProbeOutputLabels() — returns the labels that correspond to each probe value.

Available probe operations:

'value' (default): returns the probe input value.
'integrate' : returns the integral of the probe input value.
'differentiate' : returns the derivative of the probe input value.
'minimum' : returns the minimum of the probe input value.
'minabs' : returns the absolute minimum of the probe input value (always positive).
'maximum' : returns the maximum of the probe input value.
'maxabs' : returns the absolute maximum of the probe input value (always positive).

The Probe interface differs from the Analysis interface in two fundamental ways:

(1) Operations can be performed on probes (i.e., in addition to simply reporting a model value, model values (probe input values) may have operations performed on them such as integration and differentiation).
(2) Analyses are not formally part of the model structure (i.e. they are not ModelComponents), and because of this, analysis results can not be accessed with the model and state value – they can only be accessed by file at the end of a simulation. Probes, on the other hand, are ModelComponents and therefore can be accessed at any time during a simulation from the API, and can also be used to compute model values that are fed back into ths system through via custom designed Controllers. Note that Probe values can also be reported to file at the end of a simulation by attaching a ProbeReporter analysis to the simulation.

Get the number of states in the underlying SimTK::Measure.

virtual int OpenSim::Probe::getNumProbeInputs ( ) const

pure virtual

Returns the number of probe inputs in the vector returned by computeProbeInputs().

This method must be overridden for each subclass Probe.

Returns: The SimTK::Vector of Probe input values.

Implemented in OpenSim::Bhargava2004MuscleMetabolicsProbe, OpenSim::Umberger2010MuscleMetabolicsProbe, OpenSim::JointInternalPowerProbe, OpenSim::ActuatorPowerProbe, OpenSim::ActuatorForceProbe, OpenSim::SystemEnergyProbe, and OpenSim::MuscleActiveFiberPowerProbe.

std::string OpenSim::Probe::getOperation ( ) const

Return the operation being performed on the probe value.

Referenced by OpenSim::ProbeReporter::disableIntegrationOnlyProbes().

virtual OpenSim::Array<std::string> OpenSim::Probe::getProbeOutputLabels ( ) const

pure virtual

Returns the column labels of the Probe values for reporting.

This method must be overridden for each subclass Probe to provide meaningful names to the probe outputs.

Returns: The Array<std::string> of Probe labels.

Implemented in OpenSim::Bhargava2004MuscleMetabolicsProbe, OpenSim::Umberger2010MuscleMetabolicsProbe, OpenSim::JointInternalPowerProbe, OpenSim::ActuatorPowerProbe, OpenSim::ActuatorForceProbe, OpenSim::SystemEnergyProbe, and OpenSim::MuscleActiveFiberPowerProbe.

SimTK::Vector OpenSim::Probe::getProbeOutputs ( const SimTK::State & state) const

Returns the values of the probe after the operation has been performed.

Parameters

state System state from which value is computed.

Returns: The SimTK::Vector of probe output values.

bool OpenSim::Probe::isDisabled ( ) const

Returns true if the Probe is disabled or false if the probe is enabled.

void OpenSim::Probe::reset ( SimTK::State & s)

Reset (initialize) the underlying Probe SimTK::Measure.

void OpenSim::Probe::setDisabled ( bool isDisabled)

Set the Probe as disabled (true) or enabled (false).

Referenced by OpenSim::ProbeReporter::disableIntegrationOnlyProbes().

void OpenSim::Probe::setGain ( double gain)

Set the gain to apply to the probe output.

void OpenSim::Probe::setInitialConditions ( SimTK::Vector initial_conditions_for_integration)

Set the initial conditions (when the probe_operation is set to 'integrate').

void OpenSim::Probe::setOperation ( std::string probe_operation)

Set the operation being performed on the probe value.
