Satellite swarm control method based on artificial potential field method including dynamic avoidance and damping characteristics

Abstract

The invention discloses a satellite cluster control method based on the artificial potential field method including dynamic avoidance and damping characteristics, including: taking the main satellite as the center, dividing its communication area, using different artificial potential fields in different areas, so as to maintain The configuration of the satellite cluster is stable; according to the relative position and relative velocity of the members in the satellite cluster, an artificial potential field method controller including dynamic avoidance is designed centered on each member satellite to ensure that the member satellites in the cluster do not occur during the mission. Collision: In view of the increase in the demand for space missions and the fact that the number of existing satellites is not enough to complete the mission, an artificial potential field method controller including damping characteristics is designed, which can effectively ensure that newly added satellites can safely and reliably join the current cluster, Form a new cluster. This method is suitable for satellite cluster configuration maintenance, collision avoidance, and cluster reorganization under space perturbation conditions.

Description

technical field [0001] The invention relates to the technical field of satellite control, in particular to a satellite cluster control method based on an artificial potential field method including dynamic avoidance and damping characteristics. Background technique [0002] With the continuous development of aerospace technology, a group composed of multiple intelligent small satellites can share information and tasks. Although the functions of small satellites are relatively simple, they can completely realize some complex functions of traditional large satellites through networking and flight, and can Greatly reduce the cost and risk borne by satellites, and significantly enhance the flexibility and robustness of the system. The main challenge of the satellite cluster comes from the dynamic coupling between the satellite and the environment. When the satellite cluster moves in space, it will face environmental disturbances, such as J2 perturbation, air resistance and solar...

AI Technical Summary

Problems solved by technology

[0004] In the control process of the satellite cluster, not only the integrity of the cluster must be maintained, but also the collision avoidance between the cluster members should be considered. The collision avoidance strategy based on the artificial potential field method purely based on the relative position cannot meet the task requirements under some special conditions.
