Abstract

The control characteristics after the failure of the control moment gyros, the actuators for satellite attitude control, were analyzed. In particular, the situation where one out of four failed was considered. For the most commonly used pyramids and box-90 structures, the singularities and singular surfaces after failure were analyzed and compared. Dynamic equations for the process of reducing the wheel speed after the failure were derived. The process of stabilizing the angular velocity of a satellite while absorbing the momentum of the faulty module by the three normal modules was analyzed. For singular shapes, the remaining CMGs may be locked or excessively shake. The authors proposed that it can be prevented by rearranging the gimbal angles.

인공위성의 자세제어 구동기인 제어모멘트자이로의 고장에 따른 제어 특성을 분석하였다. 특히, 4개 중에 한 개가 고장난 상황을 고려하였다. 가장 많이 사용되는 피라미드와 box-90 구조를 고려하였으며, 고장 발생 이후의 특이점 및 특이면을 분석하고 비교하였다. 모듈이 고장나고 휠 속도를 줄이는 과정에 대한 동역학 방정식을 유도하였다. 정상인 세 모듈이 고장난 모듈의 모멘텀을 흡수하면서 위성의 각속도를 안정화하는 과정을 분석하였는데, 특이형상에서 나머지 CMG가 교착되거나 과도하게 요동할 수 있는데, 짐벌각 재조정을 통하여 방지할 수 있음을 제시한다.
