为了研究编队卫星在遇到各种扰动时的姿态跟踪与同步，引入信息交流拓扑图进行信息交流，使编队中卫星可以根据预定姿态、自身姿态和编队中其他可通信卫星的姿态来确定自身的控制。在不同幅值与频率的正弦扰动情况下，提出了2种卫星姿态跟踪与同步的控制律：基于退步算法和内模原理的控制律以及基于四元数辅助系统的控制律。利用Lyapunov方法，对卫星系统的全局跟踪与同步进行了证明，并且进行了仿真验证。

To investigate the attitude tracking and synchronization of formation-flying satellites with the occurrence of various per-turbations,information-communicating topological graphs are introduced to realize information communication.In this way,their own con-trol of the satellites in the formation can be determined in accordance with their preset attitudes,their own attitudes and the attitudes of other communication satellites in the formation.Two control laws for the satellite attitude tracking and synchronization are proposed under the situation of sinusoidal disturbances with different amplitudes and frequencies,i.e.,the one based on backoff algorithm and internal modeling principles,and the other on quaternion auxiliary system.The global asymptotic stability of the system is proved by using Lya-punov methods.Simulation results are provided to show the correctness.
