Formation configuration reconstruction control method based on J2 perturbation active utilization

Abstract

The invention discloses a formation configuration reconstruction control method based on J2 perturbation active utilization. The method comprises the following steps: calculating configuration parameter deviation in a formation plane; when it is judged that the angle change direction of the relative eccentricity rate vector before and after reconstruction is the same as the rotation direction of the relative eccentricity rate vector caused by J2 perturbation influence, the amplitude of the relative eccentricity rate vector is controlled, and angle change is completed based on J2 perturbation; when it is judged that the angle change direction of the relative eccentricity rate vector before and after reconstruction is opposite to the rotation direction of the relative eccentricity rate vector caused by J2 perturbation influence, in-plane configuration reconstruction is completed with time as priority; determining a strategy for performing fuel-saving out-of-plane configuration reconstruction by using J2 perturbation; and pulse control causes a master-slave satellite orbit inclination angle difference of active bias, a relative inclination angle vector y-axis component is changed based on J2 perturbation, and out-of-plane configuration reconstruction is completed. By using the invention, formation configuration reconstruction control which saves more fuel consumption than traditional analysis pulse reconstruction is realized. The method can be widely applied to the field of satellite formation configuration control.

Description

technical field [0001] The invention relates to the field of satellite formation configuration control, in particular to a formation configuration reconfiguration control method based on J2 perturbation active utilization. Background technique [0002] Satellite formation configuration reconfiguration control is an important guarantee technology for formation missions to achieve flexibility and robustness. Traditional analytical pulse reconstruction control methods for satellite formation configurations are proposed based on the assumption of a two-body model, but under the influence of the Earth's non-spherical J2 perturbation, the relative orbital elements will undergo perturbation changes. By rationally using the influence of J2 perturbation on the formation configuration parameters, intelligently using the perturbation influence, and making the most possible use of the natural perturbation influence, fuel-saving formation configuration reconfiguration control can be real...
