Control Strategy for Safe Descent of Power Assisted Wheelchair on Declining Road Using Regenerative Braking

Physically weak, senior and disabled citizens use manual wheelchairs to move around places. The electrical wheelchairs provide them this required support for movement. It is difficult to control manual wheelchairs on sloping roads and hence the use of electrical power assisted wheelchair is advantageous, which can be controlled by braking. This paper proposes a new braking control algorithm to control these wheelchairs on downhill road and during its process; it is able to regenerate some power which can be stored in a charge storing device like a battery or super capacitor.
