Abstract

This paper introduces a research on the control method design for the subsonic intake flow of a dual-combustion ramjet engine. To design the control method, the intake flow dynamic response characteristics, based on a designated flow condition and intake geometry, are investigated, and a control method concept considering the intake flow characteristics is established. Using a dynamic simulation model of a dual-combustion ramjet, control input/output linearized models are obtained such that a control loop design based on linearized models can be accomplished. Finally, from various control loop simulations, the performance of the control method, including its control loop stability, is evaluated.

본 논문에서 이중연소 램제트엔진의 아음속 흡입구 제어기법 설계에 대한 연구를 소개하였다. 제어기법 설계를 위해 유동조건 및 흡입구 형상에 기초한 흡입구 유동의 동적 응답특성을 조사하고, 흡입구 유동특성을 고려한 제어기법 개념을 설정하였다. 이중연소 램제트 동적 시뮬레이션 모델을 활용하여 시스템 입/출력 선형화 모델을 획득하였으며, 선형화 모델 기반의 선형 제어루프 설계를 수행하였다. 최종적으로, 다양한 제어루프 시뮬레이션을 통해 설계된 제어루프의 안정성을 포함한 제어기법 성능을 평가하였다.
