Control method for conducting racemization and nutation on space non-cooperative target through axial magnetic field

Abstract

The invention provides a control method for conducting racemization and nutation on a space non-cooperative target through an axial magnetic field and belongs to the technical field of space non-cooperative target racemization control methods. A disc type axial magnetic field structure composed of multiple sets of three-phase coils is designed, magnetic field source excitation parameters are controlled to form the rotating magnetic field in the space, according to the rotating state of the space non-cooperative target, each set of rotating magnetic field sources are connected or disconnected,and it is guaranteed that after superposition, the racemization force moment induced by the magnetic field on the surface of the space non-cooperative target attenuates the spinning angular speed andthe nutation angle of the space non-cooperative target all the time. The magnetic field does not need to be perpendicular to the rotation direction of the space non-cooperative target, interference ofmechanisms such as a solar panel on the space non-cooperative target in the racemization process is avoided, the nutation angle can be controlled not to diverge when the spinning angular speed of thespace non-cooperative target is attenuated, and the attitude stability of the space non-cooperative target in the racemization process is guaranteed.

Description

technical field [0001] The invention relates to a derotation and nutation control method for a space non-cooperative target by using an axial magnetic field, and belongs to the technical field of a space non-cooperative target derotation control method. Background technique [0002] A large number of remaining non-cooperative targets in space, including rocket propellers, failed satellites, spacecraft mission discards, spacecraft disintegration and collision derivatives, pose a huge threat to the development of human spaceflight, and the active movement of non-cooperative targets in space Departure work is also imminent. Usually, non-cooperative space targets have lost the ability to adjust their attitude and have been running out of control for a long time. Affected by perturbing moments such as solar light pressure, gravity gradient, and their own residual angular momentum, tumbling motions often occur. Under the action of non-active forces such as the space environment, ...

AI Technical Summary

Problems solved by technology

The existing derotation control methods for space non-cooperative targets have certain defects. For example, the derotation magnetic field source constructed with a vertical spin axis will interfere with the solar panel, and there is a risk of collision if the distance is too short. The spin effect is greatly reduced
