摘　　要：航天器间姿态与轨迹的耦合效果对于航天器在太空中的交会有着较大的影响。针对传统航天器在追踪问题上无法统一描述姿轨耦合与减小控制力、控制力矩饱和的问题,本文提出了一种自调整函数的改进型PD控制方法,更好地实现了航天器姿态与轨道的一体化控制,确保了航天器在追踪条件下的自身姿轨与追踪目标姿轨的同步性。本文利用Lyapunov函数对姿轨耦合系统进行稳定性分析,实验结果证明了本文所提方法在系统稳定性和饱和性上具有较好的控制效果。The coupling effect of attitude and trajectory between spacecraft has a great influence on spacecraft rendezvous in space. Aiming at the problems that traditional spacecraft cannot uniformly describe the coupling of attitude and orbit, reduce the control force and saturated control moment, this pa-per proposes an improved PD control method with self-adjusting function, which better realizes the integrated control of spacecraft attitude and orbit, and ensures the synchronization of spacecraft self-attitude orbit and target attitude orbit under tracking conditions. In this paper, Lyapunov func-tion is used to analyze the stability of the asis-orbit coupling system. The experimental results show that the proposed method has a good control effect on the stability and saturation of the system.
