The purpose of this review is to convey the depth and breadth of the research conducted on electric-powered wheelchair (EPW) control technology as well as provide insights into future directions. We review the concepts and previous work on velocity control, traction control, suspension control, stability control, stair-climbing wheelchairs, and wheelchair navigation. The information gathered in this study is intended to promote awareness of the status of contemporary powered wheelchair control technology and increase the functional mobility of people who use EPWs.
