Abstract

An integrated flight simulation program for multicopter drones is presented. The program includes rigid body dynamics, propeller thrust, battery energy, control, and air. Using this program, users can monitor and analyze the states of drones along flight trajectories. As a programming language, Modelica has been chosen, that specializes in simulation program development. Modelica enables users to develop simulation programs efficiently due to acausal and object oriented properties. For missions including horizontal and vertical maneuvers, many dynamical states of drones have been analyzed with simulation results.

멀티콥터형 소형 드론의 통합 비행 시뮬레이션 프로그램을 개발한 내용을 소개한다. 드론의 강체 동역학, 프로펠러 추력, 배터리 에너지 변화, 자세 및 경로 제어, 대기 상태 등을 통합적으로 시뮬레이션 하여 비행경로에 따라 드론의 상태를 분석할 수 있다. 프로그램 개발을 위하여 모델리카 언어를 선정하였는데, 모델리카는 비인과적, 객체지향적 특성을 갖추고 있어서, 프로그램 개발의 효율을 높일 수 있다. 수평 수직 이동이 포함된 가상 임무에 대하여, 시뮬레이션 결과를 이용하여 드론의 동적 거동을 분석하였다.
