Problems solved by technology

On the one hand, the reconfigurability optimization methods of existing spacecraft systems do not consider the impact of external disturbances such as harsh operating environments and unique operating conditions; in fact, the existence of interference will accelerate the deterioration of faults and cause control deviations Proliferation and waste of finite resources, thereby weakening the actual reconfiguration potential of the system

On the other hand, in actual engineering, the method of increasing hardware backup redundancy is often used to improve the reconstruction control capability of the system; however, due to factors such as cost and weight, the number of backups that the spacecraft can carry is limited; Hardware redundancy. Switching hardware devices (especially actuators) during the operation of the spacecraft will affect the stability of the system to a certain extent. landing conditions) are not permitted
