초록

넓은 비행마하수와 받음각 기동 조건에서 고정된 형상을 가지는 초음속 흡입구에 안정되고 높은 압축비의 공기를 공급할 수 있는 제어기법을 제안하였다. 다양한 선행연구 결과 분석을 통하여 가장 현실적으로 적용하기에 용이한 제어변수를 도출하였고, 이를 비행조건에서 스케줄링 하여 사용할 수 있는 방법을 제시하였다. 제안된 스케줄링 및 흡입구 전압력 회복율 제어기를 추진기관 모델과 결합하여 시뮬레이션 함으로써 다른 제어변수에 비해 광범위한 비행영역에서 운용하기에 적합한 방법임을 보였다. 아울러 다양한 비행 조건에서의 제어기의 안정화 및 추종 성능을 시뮬레이션 함으로써 엔진의 동적 특성과 비행 기동역학 및 외란에 의해 나타나는 특성에 대해 살펴보았다.

Buzz margin scheduling and control technique which are suitable to regulate stable and high pressure air in wide range of Mach number are suggested for fixed geometry of a supersonic intake. From the analysis of preceding study, most effective control variable is induced and scheduling law is newly suggested in a real application point of view. The appropriateness of the control law in wide range of Mach number is addressed by numerical simulation of controlled propulsion system. Also, the simulation for stabilization and tracking performances of the controller are studied to investigate the phenomena under flight maneuver and disturbances.
