State target based heuristic spacecraft mission planning method

Abstract

The invention discloses a state target based heuristic spacecraft mission planning method, relates to a spacecraft mission planning method, and belongs to the technical field of aerospace. According to the characteristics of spacecraft system constraint complexity and system state information intercoupling, multiple parallel subsystems of a spacecraft are depicted by the aid of multidimensional timelines; according subsystem constraint characteristics, timelines satisfying timeline parametrization screening conditions are subjected to timeline parametrization processing to reduce searching space of problems; meanwhile, state and defect selection heuristic design is performed according to target information of state, prioritized selection is performed on the state with the highest weight and the defect with the highest evaluation value to ensure realization of mission targets, and spacecraft mission planning efficiency is increased. Problem searching and solving rate in spacecraft mission planning can be increased, rational planning solutions are obtained within shorter time, and the problem of low planning efficiency caused by planning operation is solved.

Description

technical field [0001] The invention relates to a spacecraft mission planning method, in particular to a state-objective-based heuristic spacecraft mission planning method, which belongs to the technical field of aerospace. Background technique [0002] The aerospace field is one of the main fields of world technological development in the 21st century. Due to the characteristics of spacecraft in space missions, such as being far away from the earth, long flight time, and dynamic environment, there are great challenges in the operation and control of spacecraft, such as long-term communication delay problems, long-term reliability problems, Real-time control issues, etc. [0003] With the development of the aerospace field, the way of spacecraft highly dependent on ground control is becoming increasingly unsuitable for increasingly complex space activities. Therefore, it is necessary for the spacecraft to complete mission planning autonomously, reduce dependence on ground ...
