레이저 영상 감지 및 거리 측정(LIDAR)은 자율주행을 위한 핵심 센서 중 하나입니다. 특히 차량의 전방 방향으로 측정 가능한 거리의 성능을 향상시키기 위해 본 논문에서는 사이클로정지 명령 신호를 이용한 BLDC(Brushless DC) 모터의 급속 회전 속도 제어를 제시합니다. 이를 통해 지정된 방향에 대한 신호 통합 시간을 늘릴 수 있어 평균 회전 속도를 유지하면서 신호 대 잡음비(SNR)가 향상됩니다. 우리는 속도 변화를 향상시키기 위해 명령 신호를 수정함으로써 모터의 회전 속도를 빠르게 가속 및 감속하는 프리엠퍼시스 회로의 사용을 제안합니다. 적응형 신호 처리는 프리엠퍼시스 필터의 계수를 자동으로 조정하여 모터와 컨트롤러의 감쇠된 응답을 보상할 수 있습니다. 20W BLDC 모터를 사용한 실험은 제안된 기술이 한 회전 동안 분당 600~1400회전(rpm) 범위의 지정된 속도 프로파일을 추적하기 위해 실제 회전 속도 출력을 달성할 수 있음을 입증합니다.

Abstract: A laser imaging detection and ranging (LIDAR) is one of the key sensors for autonomous driving. In order to improve its performance of the measurable distance, especially toward the front-side direction of the vehicle, this paper presents rapid revolution speed control of a brushless DC (BLDC) motor with a cyclostationary command signal. This enables the increase of the signal integration time for the designated direction, and thus improves the signal-to-noise ratio (SNR), while maintaining the averaged revolution speed. We propose the use of pre-emphasis circuits to accelerate and decelerate the revolution speed of the motor rapidly, by modifying the command signal so as to enhance the transition of the speed. The adaptive signal processing can adjust coefficients of the pre-emphasis filter automatically, so that it can compensate for the decayed response of the motor and its controller. Experiments with a 20-W BLDC motor prove that the proposed technique can achieve the actual revolution speed output to track the designated speed profile ranging from 600 to 1400 revolutions per minute (rpm) during one turn.
