Abstract
The aim of this study was to develop and test feedback control strategies for integration of elec- tric motor assist and functional electrical stimula- tion for paraplegic cycling. An integrated two-loop feedback control strategy is proposed, in which the electric motor is driven to provide feedback con- trol of cycling speed, and the cyclist's leg power is controlled by automatic variation of stimulation intensity. Representative experimental results are presented for one complete-lesion paraplegic sub- ject. The results show accurate feedback control of: cycle cadence; leg power; and external distur- bance rejection. We conclude that the addition of electric motor assist, with an integrated feedback control strategy, can compensate for external dis- turbances, it can greatly increase the overall power output and thereby signicantly extend the range of operation, and it can provide optimal operating conditions for the stimulated muscles.
