Repetitive Learning Control for Functional Electrical Stimulation Cycling with Antagonistic Biarticular Muscle

Abstract

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.
