Study on Disturbing Moment Compensation for the Satellite with Large-Scale Rotating Antennas

In this paper, a method of interference feedforward compensation is proposed for the disturbance of satellites with large rotating antenna such as relay satellites with Large-scale Rotating Antennas. This method utilizes the angular momentum exchange device in advance to pre-compensate In order to reduce the disturbance of the satellite by calculating the coupling angular momentum changes of the satellite caused by the antenna motion at different positions. The simulation results show that the method can effectively reduce the interference of satellite when antennas do large-scale rotating which can make the attitude of the satellite more stable and the directional fluctuation of the platform smaller, which is conducive to the normal work of other satellite loads.
