空间四面体构型在空间物理场三维立体协同探测任务中具有重要应用价值。为了保证空间四面体良好的探测性能,必须对空间四面体构型进行构型维持控制。但是,在法向控制中,法向机动的切向耦合效应会导致编队构型发生切向漂移,使得空间四面体几何特性变差,从而影响编队卫星的探测性能。针对编队飞行任务,通过解析的补偿方法消除法向机动时由于耦合效应造成的构型切向漂移,从而实现J2摄动下精确的构型初始化重构和构型保持控制。仿真表明,该方法简单有效,能够有效消除J2摄动下的法向机动引起的构型切向漂移,实现更精确的构型控制。
Spatial tetrahedral configuration has important application value in the cooperative task of three-dimensional space physics exploration. In order to ensure the good detection performance of the tetrahedron, it is necessary to control the configuration of the tetrahedral structure in space. However, in the normal control, the tangential coupling effect of the normal maneuver can lead to the tangential drift of the formation formation, which makes the geometric properties of the space tetrahedron deteriorate, which affects the detection performance of the formation satellites. Aiming at the formation mission, the configuration tangential drift due to the coupling effect in normal maneuver is eliminated by the analytical compensation method, so as to realize the accurate configuration initialization and configuration keeping control under J2 perturbation. The simulation results show that the proposed method is simple and effective and can effectively eliminate the configuration tangential drift caused by normal maneuvering under J2 perturbation and achieve more accurate configuration control.
