Embodiment Construction

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention.

[0027] Before explaining the embodiments of the present invention, it is necessary to explain the meaning of the term "hierarchical task network planning" used in the embodiments of the present invention. Hierarchical task network planning is to represent the system state by a set of atomic propositions, and the actions correspond to Determines state transitions. The purpose of hierarchical task network planning is to achieve a collection of certain tasks. The input to hierarchical task network planning contains not only a set of actions but also a set of methods. The process of hierarchical task network planning is to recursively decompose non-atomic tasks into smaller and smaller subtasks until there are atomic tasks that can be completed by directly executing the planning ...

Abstract

The embodiment of the invention discloses a method for planning modular reconfigurable satellite self-reconfiguration based on a hierarchical task network. The method is applied to a modular reconfigurable satellite and comprises the following steps of: acquiring an initial position matrix corresponding to the initial configuration of a modular reconfigurable satellite and a target position matrix corresponding to a target configuration expected by the self-configuration task of the modular reconfigurable satellite based on a set description coordinate system; determining the moving task of each module in the modular reconfigurable satellite according to the initial position matrix and the target position matrix by using an analytic hierarchy process; and generating a module motion instruction corresponding to each module according to the moving task of each module, wherein the module motion instruction is used for controlling the motion sequence of the motion device installed at each module to perform self-reconfiguration for each module according to the target configuration.

Description

technical field [0001] The embodiment of the present invention relates to the field of satellite technology, in particular to a method, device and computer storage medium for self-reconfiguration of a modular reconfigurable satellite based on hierarchical task network planning. Background technique [0002] Modular reconfigurable satellite is a new concept satellite proposed in order to comply with the development trend of future satellites. It is composed of isomorphic modules with different functions, the same shape and interchangeability. These isomorphic modules can include functional modules such as propulsion modules, navigation modules, and power modules, as well as structural modules and specific payload modules. The overall configuration of the satellite can be changed by moving each isomorphic module, thereby adapting to on-orbit assembly and self-adaptive on-orbit assembly. Orbit services, space pre-deployment to deal with emergencies and other different mission r...
