基于摄动的不稳定编队协同控制系统仿真

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。

Coordinated Control System Simulation of Unsteady Spacecraft Formation Based on Perturbation Effect

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,gene...
