编队卫星构形精确保持是实现分布式卫星任务的关键技术。基于摄动对编队相对轨道构形的影响,针对卫星轨道半长轴有偏差的不稳定编队,设计了一种基于视线测量无主星编队的循环协同控制系统。编队中每一颗卫星跟踪自己轨道前方邻近卫星,产生一个视线测量矢量,编队的第一颗卫星追踪最后一颗卫星,产生循环编队,将编队卫星之间的视线距离作为反馈控制量来实现队形控制,文章给出了相对摄动力方程和控制系统的仿真算例,仿真结果表明,该循环协同控制系统能够实现队形控制的稳定性。
The precise keeping of the formation satellite formation is the key technology to realize the distributed satellite mission. Based on the influence of perturbation on the relative orbital configuration of formation, aiming at the unsteady formation with deviation of the semi-major axis of satellite orbit, a cyclical coordinated control system based on line-of-sight measurement without main star formation was designed. Each satellite in the formation tracks the neighboring satellites in front of its orbit, generating a line-of-sight measurement vector. The first satellite in the formation tracks the last satellite and generates a cyclic formation that takes the line-of-sight distance between formation satellites as the feedback control volume The paper gives the simulation example of relative perturbation equation and control system. The simulation results show that the cyclic cooperative control system can realize the stability of formation control.
