摘要： 基于空间飞行器的轨道动力学原理,利用混杂系统模型研究了悬停轨道问题,建立了悬停轨道的混杂系统模型;借此模型,针对目标星轨道为椭圆的情况,提出了等距离悬停轨道控制和椭圆悬停轨道控制两种方案,分别推导出在这两种方案下对悬停星所施加的控制力。数值仿真结果表明,分别对悬停星施加相应的控制力,能够实现对目标星的悬停。

Abstract: Based on the dynamical principle of spacecraft orbits,the hybrid system model was used to study the hovering problems and a hybrid system model of hovering orbits was established.Based on this model,in the case that the target satellite orbit is elliptic,an equidistant hovering orbit control scheme and an elliptical hovering orbit control scheme were proposed,and the corresponding forces exerted on the hovering satellite for these two schemes were derived respectively.Numerical simulation results showed that hovering movement can be realized by exerting the corresponding forces on the hovering satellite.
