The invention discloses a giant constellation continuous coverage configuration keeping control method. The giant constellation is formed by combining a plurality of sub-constellations operating on a low-orbit circular orbit, the satellite orbit semi-major axes of the sub-constellations are equal, and the constellation continuous coverage constraint and atmospheric perturbation influence are analyzed and decomposed into ascending node right ascension constraint, relative motion boundary constraint between coplanar adjacent satellites and satellite orbit height constraint. And respectively designing an out-of-plane control potential function, an inter-satellite boundary control potential function and a semi-major axis control potential function aiming at the constraints. The constellation control method only depends on the motion state of the controlled satellite and the motion state of the coplanar adjacent satellites, constellation global information does not need to be obtained, and therefore the constellation control method is a completely-distributed decentralized self-organizing control method.

    本发明公开了一种巨型星座连续覆盖构型保持控制方法。所述巨型星座是由运行在低轨圆轨道上的多个子星座组合而成,每个子星座的卫星轨道半长轴相等,针对星座的连续覆盖约束及大气摄动影响解析分解为升交点赤经约束、共面相邻卫星间的相对运动边界约束以及卫星轨道高度约束,并针对上述约束分别设计面外控制势函数、星间边界控制势函数和半长轴控制势函数。该星座控制方法仅依赖受控星运动状态和共面相邻卫星的运动状态,无需获取星座全局信息,因此是一种完全分布式分散化的自组织控制方法。
