Abstract:
1. A myoelectric controller for a weight bearing member having at least one powered joint, comprising: a non-transitory computer-readable medium; a velocity reference module stored in the computer-readable medium and configured for receiving myoelectric control signals from a user during a non-weight bearing mode for the at least one powered joint and generating a velocity reference for the at least one powered joint based on the myoelectric control signals; a volitional impedance module stored in the computer-readable medium and configured for generating a torque control signal for actuating the at least one powered joint based at least on the velocity reference; and a classification module stored in the computer-readable medium and configured for determining an intent of the user based on one of quadratic discriminant analysis of the myoelectric control signals and linear discriminant analysis of the myoelectric control signals, wherein the velocity reference module uses the intent of the user determined by the classification module to generate the velocity reference.
