The invention relates to a separated satellite pointing control composite formation experiment method. Firstly, a satellite body and a load module are in electromagnetic locking connection or the load module is actively controlled to follow the satellite body, and the satellite body adopts a conventional attitude execution mechanism to carry out coarse precision pointing control on a target and coarse formation control between the satellite bodies. Afterwards, the separated electromagnetic actuator is released, two-axis translation control force and single-axis pointing control torque are generated, and high-precision pointing of the load modules to the target and relative motion control between the load modules are carried out. And finally, after the formation is stable, the satellite body tracks the direction of the load module, the relative position between the modules is maintained to prevent the modules from colliding, and finally the multiple separated experimental satellites cooperate together to realize direction control composite formation. According to the method, a separated satellite design is adopted, a separated multi-degree-of-freedom control system is designed between a satellite body and a load module, and high-precision and high-stability control is performed on the direction of the load module through secondary formation.

    本发明涉及一种分离式卫星指向控制复合编队实验方法。首先将卫星本体与载荷模块进行电磁锁紧连接或主动控制载荷模块跟随卫星本体,卫星本体采用常规姿态执行机构对目标进行粗精度指向控制及卫星本体间粗编队控制。其后,分离式电磁作动器释放,生成两轴平移控制力及单轴指向控制力矩,进行载荷模块对目标高精度指向及载荷模块间相对运动控制。最后待编队稳定后卫星本体对载荷模块的指向进行跟踪,维持模块间相对位置防止模块发生碰撞,最终多颗分离式实验卫星共同配合实现指向控制复合编队。本方法采用分离式卫星设计,在卫星本体和载荷模块之间设计分离式多自由度控制系统,通过二级编队对载荷模块指向进行高精度高稳定度控制。
