A wheelchair driven with fuzzy logic controlled switched reluctance motor supplied by PV arrays

Abstract

In this study, destination capacity of wheelchairs has been increased by using a photovoltaic source, boost converter and employing SRM to drive wheelchair. An intelligent speed controller based on fuzzy logic was developed to increase comfort of disabled people. In addition, an accelerometer was used to measure acceleration, which is directly related to passenger comfort. All these improvements were implemented by means of a PIC18F452 microcontroller due to its low cost and superior performance. © 2008 Asian Network for Scientific Information.
