This paper deals with repetitive learning control for functional electrical stimulation (FES) pedaling exploiting pedal force direction with antagonistic biarticular muscles . FES pedaling motion with muscle contraction is expressed as an Euler Lagrange system. Asymptotic tracking for the closed-loop system by the proposed controller is analyzed through Lyapunov-based methods. Experiments were conducted in three healthy individuals to show the validity of the proposed method from a practical point of view.
