EMG Method and Apparatus for Continuous Control of Electric Wheelchair using EMG

摘要

An electric wheelchair control method and apparatus using EMG are presented. An electric wheelchair control method using the proposed EMG includes receiving a plurality of EMG signals using an EMG sensor attached to a wheelchair user, extracting a user''s intention from the received plurality of EMG signals, And controlling the direction and the velocity of the wheelchair by using the generated control signal. Wherein the step of extracting a user''s intention from the received plurality of EMG signals and performing a signal processing and a correction for using the plurality of EMG signals in combination to generate a control signal includes generating an RMS signal Acquiring an envelope using the EMG signal, normalizing the RMS signal to match the levels of the inputted plurality of EMG signals, performing SPW signal processing and correction to use the plurality of EMG signals in combination, And generating a control signal for continuously controlling the wheelchair according to the intention of the user using the RMS signal and the SPW signal processing
