摘要
为解决未来交会对接任务的自主化问题,提出航天器远程自主交会方法。给出适用于远程自主交会的变轨策略,设计航天器上自主变轨规划算法,通过初值计算和精确解迭代两个步骤对变轨策略进行求解,获得变轨控制参数。采用拟平均根数法结合平均密度法进行轨道预报,在尽量保证模型精度的同时极大降低了轨控参数求解过程中的在轨计算量。仿真结果表明,使用该方法规划的远程导引段轨道控制,可使终端精度满足指标要求,且方法简单可靠、合理可行,具有工程应用价值。
In order to realize automatization in rendezvous and docking mission,a method of long distance autonomous rendezvous for spacecraft is proposed. A maneuver strategy adapted to long distance autonomous rendezvous is designed.The control parameters are obtained by the autonomous maneuver plan algorithm which contains the initial value calculating and accurate solution iterating. The quasi-mean element method combined with the mean atmosphere density method is used to reduce the on-orbit calculation quantity. The simulation result shows that the design variables of this method satisfy the terminal conditions well.
