Abstract

In this paper, a novel torque control scheme is proposed and implemented to handle the torque level of ebike precisely. By adopting moving average filters to eliminate throttle noise, ebike driver could control throttle level on wide span of 256 steps. Designed controller is plugged into ebike and tested to demonstrate it's linear control incomparable to conventional cadence sensing controller.

본 논문에서는 전기자전거의 정밀 토크제어를 위하여 새로운 토크제어 방식을 제안하고 구현한다. 트로틀 노이즈를 제거하기 위한 이동 평균 필터를 채택함으로써 256 단계의 세분화된 트로틀 단계로 전기자전거의 제어가 가능하다. 설계된 컨트롤러는 전기자전거에 장착 실험되어 기존의 Cadence 감지 컨트롤러 대비 개선된 선형 제어특성을 확인하였다.
