Autonomous Control System for GEO Satellite Based on Hierarchical Structure

Abstract

Aiming at the problem of how to realize autonomous control of spacecraft, this paper designs autonomous control system based on hierarchical structure with geosynchronous orbit (GEO) satellite as the background. The system takes into account the control structure, task requirements, fault diagnosis and reconstruction, etc. The system adopts a three-layer hierarchical structure, namely the organizational planning layer, the distribution coordination layer and the real-time execution layer. The organization planning layer is responsible for controlling the generation of tasks, and undertakes, manages and intelligently decides the control tasks; the coordination layer is responsible for coordinated control strategy, and fault diagnosis and reconstruction; real-time execution layer is responsible for information acquisition, and execution control strategy. In this paper, the detailed design and analysis of the mechanism of the autonomous operation of the system are carried out, and the specific control algorithms and control strategies involved are briefly described. At the end of the paper, the designed system is used to verify the normal working stage of a certain type of satellite platform. The results show that the system designed in this paper can effectively realize the autonomous operation of the spacecraft, which proves that the system is feasible and effective, with engineering application value.
