Systems and methods for approximating musculoskeletal dynamics

A method for controlling a device comprising:

• receiving, by a controller, at least one biological signal from a residual limb;
• expanding, by the controller, the at least one biological signal into one or more activation signals based at least in part on a polynomial associated with musculoskeletal dynamics of the residual limb;
• transforming, by the controller, the one or more activation signals into one or more intended motion signals based at least in part on a plurality of approximated muscle dynamics;
• and
• transforming, by the controller, the one or more intended motion signals into one or more control signals.

A system comprising:

• a controller comprising a processor, the controller configured to at least:
• receive at least one biological signal from a residual limb;
• execute a signal processing algorithm to expand the at least one biological signal into one or more activation signals based at least in part on a polynomial associated with musculoskeletal dynamics of the residual limb;
• execute a modeling algorithm to transform the one or more activation signals into one or more intended motion signals based at least in part on a plurality of approximated muscle dynamics;
• and
• execute a control algorithm to transform the one or more intended motion signals into one or more control signals.
