The invention relates to a combined unloading method and system based on angular momentum of a flywheel and a control moment gyroscope. The method comprises the following steps: calculating angular momentum to be unloaded of the flywheel; calculating to-be-unloaded angular momentum of the moment gyroscope; calculating star angular momentum; calculating the total magnetic unloading angular momentum; calculating a total magnetic unloading current; carrying out combined unloading control on the angular momentum of the flywheel and the control moment gyroscope according to the total magnetic unloading current; compared with the prior art, the method has the advantages that the to-be-unloaded quantities of the flywheel and the moment gyroscope are converted into the to-be-unloaded angular momentum for the spacecraft adopting the hybrid actuating mechanism, meanwhile, the influence of the star angular momentum is considered, the whole star angular momentum is controlled within a certain range, the unloading problem based on attitude control of the hybrid actuating mechanism is solved, and the unloading efficiency is improved. And the method has better engineering realizability.

    本发明涉及一种基于飞轮和控制力矩陀螺角动量的联合卸载方法及系统,包括如下步骤:计算飞轮待卸载角动量;计算力矩陀螺待卸载角动量;计算星体角动量;计算总磁卸载角动量;计算总磁卸载电流;根据总磁卸载电流进行飞轮和控制力矩陀螺角动量的联合卸载控制;与现有技术相比,本发明针对采用混合执行机构的航天器,将飞轮和力矩陀螺的待卸载量都转换为待卸载角动量,同时考虑星体角动量的影响,将整星角动量控制在一定范围内,该方法解决了基于混合执行机构姿态控制的卸载问题,具有较好的工程可实现性。
