Abstract :
This study evaluated an adaptive control system (the PG/PS control system (see J. J. Abbas and H.J. Chizeck, vol. 42, p. 1117-27, 1995)) that had been designed for generating cyclic movements using functional neuromuscular stimulation (FNS). Extensive simulations using computer-based models indicated that a broad range of control system parameter values performed well across a diverse population of model systems. The bet that manual tuning is not required for each individual makes this control system particularly attractive for implementation in FNS systems outside of research laboratories.
