Abstract

A modeling and power simulation of a small UAV's electric propulsion systems is described. Each power source is modeled and simulated in Matlab/Simulink and it is compared flight test data during 4 hr 30 min with simulation results about 200 W electric propulsion system using fuel cell and battery as a main power sources. In result, it is properly simulated performance and dynamic characteristic of each electric power source. Through this, it is revealed that the simulation is available as a means of predicting power characteristic variation for electric propulsion systems of different class.

본 논문에서는 소형 무인기의 전기추진 시스템에 대한 모델링 및 전력 시뮬레이션에 관하여 기술하였다. 각 전력원 모델링 및 시뮬레이션을 위해 Matlab/Simulink를 사용하였고, 연료전지와 배터리를 주 전력원으로 사용하는 200 W급 전기추진 시스템에 대하여 4시간 30분의 비행 시험결과와 시뮬레이션 한 결과를 비교하였다. 그 결과, 시뮬레이션은 각 전력원의 성능 및 동특성을 적절히 모사하였고, 이를 통해 다른 급의 전기추진 시스템에 대한 전력특성변화를 예측하는 도구로 활용 가능함을 알 수 있었다.
