| Summary: | FES induced movement control is a significantly
challenging area due to complexity and non-linearity of musculoskeletal
system. The goal of this study is to design a cycle-to-cycle
control of FES-induced swinging motion. In this approach only
the quadriceps muscle is stimulated by controlling the amount of
stimulation pulsewidth. This time dependent behaviour is
successfully compensated for using a cycle-to cycle fuzzy
controller, which computes the amount of knee extension
stimulation on the basis of the achieved flexion angle in previous
cycles.The capability of fuzzy control in automatic generation of
stimulation burst duration is assessed in computer simulations
using a musculo-skeletal model. This paper presents the
development of a fuzzy logic control scheme based on discretetime
cycle to cycle control strategies without predefined
trajectory. The results show the effectiveness of the approach in
controlling FES-induced swinging motion |
