Progression Week 1

Project Description

In recent times, the use of wheelchairs has increased rapidly. This is because with the aging of the current population, the demand for wheelchairs is increasing not only among the disabled but also among the increasing aged population. Therefore, I want to develop a new controller for power-assisted wheelchairs. Conventional power-assist controllers only focus on the amplification of the human input force using torque sensor. the proposed controller does not use a torque sensor but an electromyogram sensor to estimate the driver’s intention. I also use a disturbance observer to compensate for the lack of propelling torque information since it is difficult to simply regard the myoelectric signals as propelling torque. Then, I decide assist torque by combining the filtered myoelectric signals and the estimated human torque signal calculated by the disturbance observer. Experimental results show that the proposed power-assist method realizes fast, stable, and smooth acceleration. With the help of exploitation of myoelectric signals, disabled persons can have a chance to improve their life with their muscle movements.
