Subject Intention Speed Control Of Electric Wheelchair For Person With Disabilities Using Myoelectric Signals

Electric wheelchair used to help mobility of disabilities person be more independent. In the development of electric wheelchair technology, electric wheelchairs can be controlled using myoelectric signals. In previous studies of electric wheelchairs with myoelectric, the using of adaptive myoelectric signals for needs of speed changes has not become a focus. In this study design thresholding process with an adaptive threshold, then compare adaptive threshold process with analog circuit and programming algorithm. Furthermore, control wheelchair speed based on subject intention variable speed is designed which Carpi Radialis muscle movements. Results of the threshold process in the myoelectric system to determine the classification of wheelchair changes are more effective in using a programming algorithm than using an analog circuit, which is proven by a success rate of 92%. In this study, PID control system would be appropriate method for maintaining wheelchair balance and for control speed of a wheelchair.
