A method, device and computer storage medium for self-reconfiguration of a modular reconfigurable satellite based on hierarchical task network planning

Abstract

The embodiment of the present invention discloses a method for self-reconfiguration of a modular reconfigurable satellite based on hierarchical task network planning; the method is applied to a modular reconfigurable satellite, and the method includes: based on a set description coordinate system Obtaining the initial position matrix corresponding to the initial configuration of the modular reconfigurable satellite and the target position matrix corresponding to the desired target configuration of the self-reconfiguration task of the modular reconfigurable satellite; using the analytic hierarchy process, Determine the movement task of each module in the modular reconfigurable satellite according to the initial position matrix and the target position matrix; generate the module motion instruction corresponding to each module according to the movement task of each module; wherein, the The module movement instructions are used to control the action sequence of the movement devices installed in the modules so as to self-reconfigure the modules 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...

Problems solved by technology

[0004] In view of the existing conventional technologies mentioned above, when realizing the on-orbit self-reconfiguration task of the modular reconfigurable satellite, the following problems will be brought about: First, the structure span of the linear configuration is relatively large, and the complex space environment where the satellite is located , The damping is small, and the large vibration generated by the linear configuration during the module rotation process is not easy to attenuate; Low energy requirements in missions
