Adaptive Control of Electrically Stimulated Muscle

A discrete time adaptive control system for electrically stimulated muscle has been designed and evaluated experimentally. The control system is based on a previously developed discrete time model of electrically stimulated muscle. Performance was evaluated on the basis of stability and responses to step, ramp, and sinusoidal inputs. Cat tibialis anterior muscles that had been previously electrically exercised were activated to control ankle joint torque via chronically implanted epimysial electrodes.
