摘　　要：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。Precise formation keeping is a key technology for the distributed satellite systems.Based on the impact of perturbation for the relative orbit configuration,a cyclic coordination control method which applied the line-of-sight measurement and leaderless formations,was proposed,focusing on the unsteady formation of semi-major axis error.Line-of-sight measurement was generated when each satellite in the formation tracked the neighbouring one in the front on the orbit and the first one tracked the last one,generating the cyclic formation.The formation control was realized via taking the lines-of-sight distances as the feedback control.Equations of the relative perturation and simulation example of the control system laws were proposed,and control validity was analyzed.The simulations demonstrate the stability of formation control can be achieved via this system.
