Derotation and nutation control method for space non-cooperative target using axial magnetic field

Abstract

The invention provides 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. The present invention designs a disk-type axial magnetic field source structure composed of multiple sets of three-phase coils. By controlling the excitation parameters of the magnetic field source, a rotating magnetic field is formed in space, and each group of rotating magnetic field sources is turned on and off according to the rotation state of the non-cooperative target in space. , to ensure that the derotation torque induced by the superimposed magnetic field on the surface of the space non-cooperative target always attenuates the spin angular velocity and nutation angle of the space non-cooperative target. In the present invention, the magnetic field does not need to be perpendicular to the rotation direction of the space non-cooperative target, which avoids the interference of the solar panels and other mechanisms on the space non-cooperative target on the derotation process, and can control the nutation angle while attenuating the spin angular velocity of the space non-cooperative target No divergence, ensuring the stability of the attitude of the non-cooperative target in space during the derotation process.

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 In addition to 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 environm...

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
