Modeling and FES control of human movement with threshold control theory

Our study aims to build a physiology-based control model of the human motor system. In the perspective of control engineering, an ideal controller is expected to drive the complex motor system without solving the “inverse dynamics problem”. Thus many researchers have suggested that the threshold con...
