Abstract

The invention relates to the technical field of spaceflight, and provides a satellite cluster distributed control method and device. The method comprises the steps of initializing the orbit parameter of a target satellite, the position parameter of each space debris, and the position parameter of each satellite in a satellite cluster; mapping the satellite cluster into a pigeon group according to the orbit parameter, the position parameter of each space debris and the position parameter of each satellite, and determining a pigeon group interaction mode according to the pigeon group; and calculating pigeon control input according to the pigeon group interaction mode, mapping the pigeon group back to the satellite cluster based on the pigeon control input, and drawing a satellite cluster trajectory. According to the method, the robustness of the large-scale satellite group system in the clustering process is improved, and the calculation load on a single satellite is reduced, so that the autonomous clustering capability of the satellite group system in a complex environment is effectively improved.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a satellite cluster distributed control method and device. Background technique [0002] With the rapid development of the aerospace industry, the number of space missions is increasing and the complexity of missions is increasing. Traditional solutions based on a single large spacecraft often have defects such as high development costs, poor in-orbit flexibility, and limited single-body capabilities. Therefore, The application and development of satellite clusters has become the future trend and strategic focus of today's space development. Satellite cluster system, as a distributed satellite system, can realize information interaction and task collaboration by keeping multiple satellites in a relatively close space area with the help of inter-satellite communication links, and complete complex on-orbit tasks. The rapid changes and the slow response of artificial assistance ...
