Abstract

In this paper, we address the problem of designing and implementing an oil pump control system driven by a brushless DC (BLDC) motor. The proposed oil pump plays the role of providing fuel to the engine clutch and transmission of hybrid vehicles. Main consideration is given to enhancing response feature and accuracy of the oil pump by simplifying the controller that is driven by a BLDC motor under PWM voltage control, which is a standard control method for BLDC motors. The proposed control scheme also helps to increase efficiency and reliability of the oil pump system. To validate the performance of the proposed system, we conduct experiments on BLDC motor speed control and oil pump operations.

본 논문에서는 BLDC 모터로 구동되는 오일 펌프 제어 시스템을 설계하고 구현하는 문제를 다룬다. 제안된 오일 펌프는 하이브리드 차량에 장착되어 엔진 클러치와 변속기에 충분한 양의 작동유를 공급하는 역할을 한다. BLCD 모터로 구동되는 제어기를 단순화하여 전원 전압을 PWM 방식으로 직접 제어하는 일반적인 방법을 사용함으로써 응답성 및 정확성을 향상시키는 것을 주목적으로 한다. 제안된 제어 기법은 오일 펌프 장치의 효율성과 신뢰성을 높인다. BLCD 모터의 회전과 오일 펌프 가동 실험을 실시하여 제안된 기법의 성능을 검증한다.
