在航天器编队飞行过程中,可能由于通信故障并非所有航天器都能直接获得参考信息,系统通信拓扑结构也可能发生变化。为了提高航天器编队系统的鲁棒性、降低生产成本等,本文在仅有部分航天器能直接获得参考信息和变化通信拓扑结构图的条件下,研究了一种基于一致性理论的航天器编队飞行协同控制方法,并通过仿真来验证其有效性。首先,介绍了航天器编队飞行中的一致性问题和动力学模型。然后,设计航天器编队飞行协同控制律,包括航天器编队飞行姿态协同控制律和航天器编队飞行轨道构型建立与保持协同控制律的设计。最后通过数值仿真验证了控制方法的有效性,仿真结果表明所设计的航天器编队控制方法有效。
During spacecraft formation flight, reference information may not be available directly to all spacecraft due to communication failures, and system communication topologies may change. In order to improve the robustness of the spacecraft formation system and reduce the production cost, this paper studies a spacecraft formation based on the consistency theory under the condition that only part of the spacecraft can directly obtain the reference information and the topological structure of the change communication. Flight collaborative control method, and verify its effectiveness through simulation. First of all, the consistency and dynamics models of spacecraft formation flight are introduced. Then, the design of cooperative control law of spacecraft formation flight including the cooperative control law of spacecraft formation flying attitude and the establishment and maintenance of cooperative control law of spacecraft formation flight orbit configuration is proposed. Finally, the effectiveness of the control method is verified by numerical simulation. The simulation results show that the proposed spacecraft formation control method is effective.
