我们考虑了在具有人工磁场的领头航天器周围的几种带电航天器结构。在所有构型中,标称轨道都选择在参考模型的相对平衡点附近。使用线性二次型调节器控制器,我们发现在大多数情况下是可能的,并且它与平衡点的稳定性密切相关,而平衡点的稳定性又取决于前导体的轨道及其磁偶极子的旋转速率。所考虑的动力学模型显示了未来编队飞行应用的巨大潜力,因为构型的建立和维护都可以通过调整跟随航天器的装药来管理。不需要额外的控制变量。
We consider several charged spacecraft configurations around a leader spacecraft provided with an artificial magnetic field. In all configurations the nominal orbits are chosen to be about the relative equilibrium points of the reference model. Using a linear quadratic regulator controller, we find that controllability is possible in most of the cases, and it is strongly related to the stability of the equilibrium point which, in turn, depends on the orbit of the leader and the rotation rate of its magnetic dipole.The dynamical model considered shows a great potential for future formation flying applications since both, the establishment and maintenance of the configurations, can be managed by merely adjusting the charge on the follower spacecraft. No additional control variables are needed.
