摘要
针对航天器燃料最优编队初始化、重构等机动展开研究,提出了一种解析控制方法。首先将编队机动问题从状态空间转换到构型参数空间进行分析,其次基于不等式约束分别得到轨道平面内、外运动的燃料消耗下界,进一步获得燃料最优时需要满足的条件和可行的燃料最优编队机动解析解,该解形式简单,计算量小。燃料消耗量取决于相对运动尺寸参数,而最优解的存在性取决于初始状态误差。数值仿真结果验证了所提方法的有效性和准确性。
A new simple method is proposed for fuel-optimal spacecraft formation maneuver, including initialization and reconfiguration, and analytical solutions with optimal-suboptimal strategies are obtained. The method consists of two stages. Firstly, a new form of parameterization of formation maneuver state is developed for simplicity. Secondly, the out-of-plane and in-plane motion are separately studied as they are uncoupled. With the help of a useful inequality introduced and proved, the lower bound of the fuel consumption and the corresponding constraints of the the minimum total fuel consumption trol algorithm proven that the depends upon the proposed depends control forces are derived and obtained. The results show that on the relative size parameters and the existence of optimal con- the initial conditions. The numerical simulations of the two applications are method is valide and efficient.
