Abstract
본 논문은 1인승 전기차량의 임베디드 전동 제어장치 설계를 제안하였다. 제안된 임베디드 장치는 PIC18F8720 프로세서, 16Mb flash ROM, 32Mb SDRAM과 신호처리회로로 설계되었다. 제안된 1인승 전기차량은 4KW 인휠 BLDCM, <TEX>$180^{\circ}$</TEX> 도통 공간 벡터제어 3상 전압형 인버터, PID 속도제어기와 전동제어 장치와 임베디드 제어장치로 구성된다. 이 1인승 전기차량은 역 3륜 형태의 기계적인 구조를 가지고 있으며, 인휠 BLDCM과 틸팅 기능을 가지는 조향 메카니즘이 적용되었다. 또한 제안된 임베디드 전동제어장치의 성능은 PEV에 대한 Lab 실험과 도로 주행시험을 통하여 검증하였다. This paper presents the design of embedded electrical power control unit for Personal Electrical Vehicle(PEV). The embedded unit is designed using PIC18F8720 processor, 16Mb flash ROM, 32Mb SDRAM and signal condition circuits. The proposed PEV consists of 4KW in-wheel Brushless DC Motor(BLDCM), 3 phase voltage source inverter with the <TEX>$180^{\circ}$</TEX> conduction space vector PWM method, PID speed controller and the embedded control unit. The PEV has mechanical manufacture of inverse 3 wheel system, which is applied by the in-wheel BLDCM and steering mechanism with tilting function. Also, the performances of the proposed embedded electrical power control unit are verified through the lab experiment and road driving test of PEV.
