무인비행기 직렬 하이브리드 추진 시스템에서의 효율적인 배터리 공급을 위한 알고리즘 개발

Recently, the number of use of unmanned airplanes has been increased, and studies have been conducting to increase the cruising time. In the case of an unmanned airplane with a small capacity, the motor is used to drive the propeller instead of using the engine. And it uses the battery to drive the propeller motor. Instead of reducing the weight of the battery, it can be increased the cruising time by adding engines, generators and converters and performing power generation control. In this paper, we installed a current sensor between the BLDC motor drive and the battery. the algorithm that perform efficient power generation control according to the power required by the propeller is developed. And it can adjust the amount of regenerating electric power. We proposed a power generation algorithm that regenerates in response to load fluctuations, and verified it through simulations and experiments.
