Heuristic spacecraft task planning method based on state transition path reconstruction

Abstract

The invention discloses a heuristic spacecraft task planning method based on state transition path reconstruction, and belongs to the technical field of aerospace. According to internal constraint characteristics of subsystems, four factors of a spacecraft structure, task requirements, an equipment state and spacecraft capacity are comprehensively considered, and composition, resources, subsystemfunctions and various constraint conditions needing to be met of the spacecraft are described; for the characteristics of complex constraint of a spacecraft system and mutual coupling of system stateinformation, a plurality of parallel subsystems of the spacecraft are described by using a timeline, and a subsystem internal state transition diagram is established; meanwhile, heuristic informationis constructed according to the constraint relation between the states and the state conversion cost value, the planning search direction is guided according to the heuristic sorting result, and the final heuristic spacecraft task planning solving result based on state transition path reconstruction is output, so that spacecraft task planning is completed, the search space is reduced, and the taskplanning efficiency is improved. The success rate of spacecraft task execution is ensured.

Description

technical field [0001] The invention relates to a spacecraft mission planning method, in particular to a heuristic spacecraft mission planning method based on state transfer path reconstruction, and belongs to the field of aerospace technology. Background technique [0002] The aerospace field is one of the main fields of world technological development in the 21st century.
