Detailed Description

This tool solves problems in which the kinematics are prescribed and you seek the actuator (e.g., muscle) behavior that may have given rise to the provided kinematics.

The term "inverse" describes methods that estimate quantities from an observation; on the other hand, "forward" methods attempt to predict (unobserved) behavior. In this case, "inverse" refers to the multibody systems. This class can still be used to simulate muscles in a "forward" or predictive sense.

The kinematics file must provide values for all coordinates (even those labeled as dependent in a CoordinateCouplerConstraint); missing coordinates are set to NaN.

The provided trajectory is altered to satisfy any enabled kinematic constraints in the model.

Cost

By default, MocoInverse minimizes the sum of squared controls and constrains initial activation to be equal to initial excitation (to avoid initial activation spikes). To customize the cost, invoke initialize(), add costs manually, and solve the problem using the solver directly. Note, however, that kinematic states are not included in the solution if you use the solver directly.

Default solver settings

  • solver: MocoCasADiSolver
  • multibody_dynamics_mode: implicit
  • interpolate_control_midpoints: false
  • minimize_implicit_auxiliary_derivatives: true
  • implicit_auxiliary_derivatives_weight: 0.01
  • optim_convergence_tolerance: 1e-3
  • optim_constraint_tolerance: 1e-3
  • optim_sparsity_detection: random
  • optim_finite_difference_scheme: forward

If you would like to use settings other than these defaults, see "Customizing a problem" below.

MocoInverse minimizes the sum of squared controls and, optionally, the sum of squared activations. As MocoInverse becomes more mature and general, the costs will become more flexible.

Mesh interval

A smaller mesh interval increases the convergence time, but is necessary for fast motions or problems with stiff differential equations (e.g., stiff tendons). For gait, consider using a mesh interval between 0.01 and 0.05 seconds. Try solving your problem with decreasing mesh intervals and choose a mesh interval at which the solution stops changing noticeably.

Basic example

This example shows how to use MocoInverse in C++:

MocoInverse inverse;
inverse.setName("prescribed_motion");
inverse.setModel(ModelProcessor("model_file.osim") |
ModOpAddExternalLoads("external_loads.xml") |
ModOpAddReserves());
inverse.setKinematics(TableProcessor("states_reference_file.sto"));
inverse.set_mesh_interval(0.02);
MocoInverseSolution solution = inverse.solve();
solution.getMocoSolution().write("MocoInverse_solution.sto");

Customizing the tool

The example below shows how you can customize the MocoInverse tool by obtaining the underlying MocoStudy. You can change the "Default solver settings" above and add additional goals.

MocoInverse inverse;
inverse.setName("prescribed_motion");
inverse.setModel(ModelProcessor("model_file.osim") |
ModOpAddExternalLoads("external_loads.xml") |
ModOpAddReserves(1));
inverse.setKinematics(TableProcessor("states_reference_file.sto"));
inverse.set_mesh_interval(0.02);
MocoStudy study = inverse.initialize();
MocoProblem& problem = study.updProblem();
auto* emg_tracking = problem.addGoal<MocoControlTrackingGoal>("emg_tracking");
emg_tracking->setReference(TimeSeriesTable("electromyography.sto"));
auto& solver = study.updSolver<MocoCasADiSolver>();
solver.set_optim_convergence_tolerance(1e-4);
MocoSolution solution = study.solve();
solution.write("MocoInverse_solution.sto");

Do NOT change the multibody_dynamics_mode solver setting, as setting this to "implicit" is vital to how MocoInverse works.

◆ append_output_paths()

inline

Append an element to the output_paths property.

◆ clone()

MocoInverse* OpenSim::MocoInverse::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.

◆ getConcreteClassName()

const std::string& OpenSim::MocoInverse::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. See getClassName() to get the class name of the referencing (possibly abstract) class rather than the concrete object.
