Detailed Description

Computed Muscle Control (CMC) is an optimization-based control technique designed specifically for controlling dynamic models that are actuated by redundant sets of actuators whose force-generating properties may be nonlinear and governed by differential equations (and so have delays in force production).

The canonical example of such a dynamic system is the musculoskeletal system (human or animal), hence the name Computed Muscle Control.

For a complete description of the CMC algorithm consult the following references:

◆ Self

typedef CMC OpenSim::CMC::Self

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

This is generated by the OpenSim_DECLARE_*_OBJECT macros.

◆ Super

typedef TrackingController OpenSim::CMC::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.

◆ assign()

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

inlineoverride

This allows copy assignment in the Java GUI.

Exceptions

Exception if the argument is not of type CMC.

◆ clone()

CMC* OpenSim::CMC::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.

◆ getConcreteClassName()

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

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.
