The invention provides a propellant adjusting method and system for imbalanced emission of a two-component propellant, and the method comprises the steps: S1, adjusting the working time of a thruster in each direction when the thruster works, adapting to the offset of the center of mass of a satellite, and feeding back to obtain the center of mass offset of the satellite; s2, according to the mass center offset of the satellite, calculating to obtain the propellant mass of each storage tank of the satellite after the thruster works; and S3, according to the current propellant mass of each storage box and the satellite centroid target correction, analyzing and determining the propellant transfer direction and transfer mass meeting the satellite centroid target correction. By adjusting the temperature difference between different storage tanks and the valve control logic of the propelling system, balanced distribution of the mass of propellants in all the storage tanks of the satellite and optimal adjustment of the mass center of the satellite are achieved, and satellite attitude control is facilitated.

    本发明提供了一种针对双组元推进剂不均衡排放的推进剂调节方法及系统,包括:步骤S1:通过调节推力器工作时的各方向推力器的工作时间,适应卫星质心的偏移,并反馈得到卫星的质心偏移量;步骤S2:根据卫星的质心偏移量,计算得到卫星各贮箱在推力器工作后的各贮箱推进剂质量;步骤S3:根据当前各贮箱推进剂质量和卫星质心目标修正量,分析确定满足卫星质心目标修正量的推进剂转移方向和转移质量。本发明通过调整不同贮箱间温差与推进系统阀门控制逻辑,实现卫星各贮箱推进剂质量的均衡分布和卫星质心的优化调整,利于卫星姿态控制。
