초록

본 연구에서는 기계식 추진 시스템인 CODOG 구조의 통합 제어를 위하여 구성 모듈인 가스터빈 엔진의 성능 모델링 및 시뮬레이션을 수행하였다. 엔진 모델은 상위 제어기 및 타 구성 모듈과의 통합이 용이하도록 MATLAB/Simulink를 이용하였으며, 시스템의 구성 및 목적에 맞는 입/출력 설정이 가능하도록 구성하였다. 일반적으로 엔진 제작사는 엔진 및 구성요소의 성능 데이터를 제공하지 않는다. 따라서 가스터빈 엔진에 대한 모델링 기법으로 구성요소의 맵을 스케일링하여 성능 데이터를 확보하는 CMF 기법을 적용하였다. 생성한 모델 및 시뮬레이션 프로그램을 이용하여 정상상태 및 동적 해석 시험을 수행하였으며, 최종 출력 결과에 대해 최대 오차 5% 이내의 신뢰성을 확보하였다.

In this study, performance modeling and simulation of a gas turbine engine, a constituent module, was performed for the integrated control of the CODOG structure, mechanical propulsion systems. The engine model used MATLAB/Simulink to facilitate integration with the host controller and other components, and was configured to enable input/output settings suitable for the system configuration and purpose. In general, engine manufacturers do not provide performance data for the engine and components. Therefore, as a modeling method for a gas turbine, a CMF method that obtains performance data by scaling the map of components was applied. Using the generated model and simulation program, steady-state and dynamic simulation analysis tests were performed, and reliability within 5% of the maximum error was secured for the final output of power.
