Description

technical field [0001] The invention relates to the technical field of spacecraft formation reconfiguration, in particular to a reconfiguration method of a translation point spacecraft formation based on an adaptive agent model. Background technique [0002] Spacecraft formation refers to the joint formation of multiple spacecraft into a virtual large-scale spacecraft to complete tasks that are difficult for a single spacecraft. organization to ensure the completion of its tasks. When the target formation configuration is known, it is only necessary to solve the optimal trajectory of the spacecraft formation reconfiguration according to the optimal control theory. Most of the current literature and scientific research work belongs to the case of known target configuration. However, in many emergencies, the final configuration of the spacecraft needs to be determined according to the task of the formation and the actual situation. At this time, the problem of formation reco...
