Abstract

This paper presents the control logic for the momentum wheel and gimbals in the CMG system. First, the design of the control logic for the momentum wheel is described in consideration of the power consumption and stability. Second, the design of the control logic for the gimbals considering the resonance of the vibration absorber and stability is explained. Third, the measurement configuration for the force and torque generated by the CMG is described. Fourth, the results of the frequency and time response test of the momentum wheel and gimbals are shown. Last, the measurements of the force and the torque generated through the CMG are explained.

본 논문에서는 제어모멘트자이로 내 짐벌과 모멘텀 휠의 제어로직에 대해 기술하였다. 우선 소모전력과 안정도(이득여유, 위상여유)를 고려하여 모멘텀 휠의 제어로직을 설계하였다. 두 번째로는 진동흡수장치의 공진과 안정도를 고려하여 짐벌의 제어로직을 설계하였다. 세 번째로는 제어 모멘트자이로에서 발생하는 힘과 토크를 측정하기 위한 장치 구성에 대해 기술하였으며, 네 번째로는 모멘텀 휠과 짐벌의 주파수응답 및 시간응답 시험 결과를 나타내었다. 그리고 마지막으로 제어 모멘트자이로를 통해 발생한 힘과 토크를 실험적으로 측정하여 나타내었다.
