Abstract

This paper describes the design and implementation of previously developed PMU (Power Monitoring Unit) for LiPB (Lithium-ion Polymer Battery) that is electric propulsion used as unmanned aerial vehicle's power source. Improved PMU provides stable voltage and current to various sensors and elctric motors necessary during flight. Voltage and current monitoring function that is measured by improved PMU more precisely be enhanced and the monitoring channel and temperature sensor is added. To verify the improved performance of the equipment, it is integrated to electric propulsion system of unmanned aerial vehicle. PMU is calibrated through the ground test. And PMU's performance is checked through the flight test.

본 논문에서는 전기추진 무인항공기의 동력원으로 주로 사용되고 있는 리튬폴리머 배터리의 상태 모니터링을 위해 기존에 자체 개발한 동력 모니터링 장치인 PMU의 개선 및 제작에 관하여 기술하였다. 개선된 PMU는 비행에 필요한 다양한 센서와 모터의 구동에 안정적인 전압과 전류를 제공하며 모니터링 채널과 온도센서의 추가로 상태 모니터링의 정밀도가 향상되었다. 지상 시험환경을 통해 무인항공기에 탑재되는 PMU의 전압전류 측정값을 보정하고 실제 비행시험을 통해 개선된 성능을 확인하였다.
