Abstract

The control law for simultaneous pressure and thrust control of solid DACS(Divert Attitude Control System) is suggested. To regulate the two variables effectively, the control structure of sequential loop closer is applied to the system considering the physical characteristics of each variable and the weighted pseudo-inverse method is suggested to allocate effective command for indeterminate system. Also, the pressure guidance law for safe and high acceleration is applied to the homing stage to verify the effectiveness of the command distribution.

고체 추진제를 연료로 사용하는 DACS의 압력 및 추력을 동시에 제어하기 위한 제어기법을 제안하였다. 두 제어변수를 효과적으로 제어하기 위하여 각 변수의 물리적 특성을 고려한 연속형 루프 닫힘 구조를 적용하였고, 부정정 구조를 가진 제어명령을 효율적으로 분배하기 위하여 가중벡터를 이용한 의사 역행열 기법을 제안하였다. 아울러 높은 가속도를 안정적으로 획득하기 위하여 압력 유도기법을 종말 호밍구간에 적용함으로써 추력과 압력에 관한 명령 분배의 효용성을 입증하였다.
