Abstract:

In response to the urgent need for safe and reliable autonomous operation of multiple types of spacecraft, such as rockets, missiles, and satellites, in-depth research has been conducted on the reconfigurability and autonomous reconfiguration methods of spacecraft, aiming to improve the system reconfiguration capability of spacecraft under faults. Firstly, considering various practical disturbance factors such as aerodynamic torque, geomagnetic torque, gravity gradient torque, and process noise, a reconfigurability evaluation method for disturbed systems is proposed, which realizes the determination and quantification of reconfiguration capability. Then, a passive/active combined autonomous reconfiguration method is proposed, which balances the implementation effectiveness and difficulty of the reconfiguration scheme. When designing specific reconfiguration algorithms, an integrated design method of normal and fault modes is proposed, which balances the nominal performance and reconfigurability of the system and reduces the over-conservativeness of the reconfiguration scheme. Finally, the effectiveness of the proposed methods is verified through a simulation example.

Key words: spacecraft, reconfigurability, autonomous reconfiguration, passive/active combination, integrated design of normal and fault modes
