Abstract:
Methods for the control of an exoskeleton comprising at least one powered joint associated with lower limbs of a user and control systems therefrom are provided. A method includes estimating a configuration of a body of the user associated with the exoskeleton with respect to a gravity vector and computing a first control torque for the at least one powered joint that at least partially compensates gravitational dynamics of the user based on the configuration. The method further includes calculating a gravitational energy gradient for the at least one powered joint, attenuating the first control torque based at least on the gravitational energy gradient to yield a second control torque, and applying a final control torque at the at least one powered joint, the final control torque based, at least in part, on the second control torque.
