초록

순차 컨벡스 최적화 기법을 사용한 궤적 최적화로 무인기 기초 설계 형상의 성능 분석을 수행했다. 외부 공력 모델로 설계한 비선형 궤적 최적화 문제는 볼록화와 이산화를 통해 2차 원뿔 프로그램 문제로 근사 되었다. 알고리즘의 성능 향상을 위해 제약조건을 완화한 문제의 해를 초기 궤적으로 사용했다. 근사해의 반복적인 탐색으로 하강 궤적 최적화 문제들을 분석했으며 설계 형상의 구동부 성능에 따른 최대 도달 속도를 비교했다.

Sequential convex programming based performance analysis of the designed UAV is performed. The nonlinear optimization problems generated by aerodynamics are approximated to socond order program by discretization and convexification. To improve the performance of the algorithm, the solution of the relaxed problem is used as the initial trajectory. Dive trajectory optimization problem is analyzed through iterative solution procedure of approximated problem. Finally, the maximum final velocity according to the performance of the actuator model was compared.
