Adaptive Control Strategy for Ankle Assistance Using an Actuated Ankle-Foot Orthosis With Selective Adaptive Parameter Convergence
Neuro-muscular injuries affecting the peroneal nerve or ankle joint dorsiflexor muscles can lead to foot-drop (FD), characterized by a difficulty in dorsiflexing the ankle during the gait. This paper introduces mid- and low-level control strategies for providing an adaptive torque assistance at the
