Abstract

To acquire high quality image, the new generation Geostationary Meteorological Satellite in China (GMSC) adopts three-axis stabilized attitude control mode, besides an advanced control system is required to be designed to get higher pointing precision and degree of stability of the satellite. However, the ability of the control system is limited. Torque compensation technology is studied in this paper aiming at rejecting the disturbance factors, which cannot be absorbed by the control system. In the research of torque compensation technology, the main factors that influence the degree of stability of satellite are analyzed; the objects compensated are confirmed through analysis of simulation; the system technical concept of torque compensation is designed; the mathematical models of the compensated objects and compensation devices are founded; the torque compensation arithmetic is designed; the valid arithmetic of torque compensation is proved through simulation. The research provides theoretical principles to develop the new generation GMSC.
