Problems solved by technology

Some of the above control strategies can achieve the characteristics of time optimization, but they are relatively complex and the fuel consumption is not optimal. However, for long-term satellite formation control, the most fuel-efficient control is the primary task of control

Embodiment Construction

[0030] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0031] Such as figure 1 As shown, record the master star as C and the slave star as A. With the main star C as the center, the formation coordinate system Cxyz is established. The x-axis deviates from the center of the earth along the radial direction in the orbital plane of the main star, the z-axis is the normal of the orbital plane of the main star, and the y-axis is determined by the right-hand rule, and the direction is consistent with the speed direction of the main star satellite.

Abstract

The invention provides a satellite team configuring control method based on fuel consumption optimization. The satellite team configuring control method based on the fuel consumption optimization comprises the following steps: team configuring control input is calculated, plane external orbit control is judged to be carried out or not according to the control input, if the plane external orbit control is needed, a corresponding speed increment and an orbit control time are worked out, coupling influences of the plane external orbit control on orbital elements in a plane are calculated, and the control input in the plane is corrected; then the orbital elements in the plane are jointly adjusted, the coupling influences among the adjustment of the orbital elements in the plane are taken into account, and effective compensation is carried out. An appropriate value k is determined according to whether drifting is needed to achieve passive control, and a three impulse speed increment and the orbit control time are obtained through calculation. The satellite team configuring control method based on the fuel consumption optimization achieves the team control based on fuel optimization, and can control configuring initialization, configuring maintenance and reconfiguration of the satellite team under the condition of a circle-similar non-equatorial orbit.

Description

technical field [0001] The invention relates to configuration control technology of satellite formation, in particular to a satellite formation configuration control method based on fuel consumption optimization. Background technique [0002] Because satellite formations have some advantages over single satellites, many countries have invested in active research and on-orbit verification of satellite formations. The configuration control technology of satellite formation is one of the key technologies. Satellite formation configuration control includes three aspects: configuration initialization, configuration maintenance and configuration reconstruction. According to the difference in the number of orbit elements, satellite formation configuration control can be further divided into the control of the number of elements outside the orbit plane and the control of the number of elements in the orbit plane. [0003] The existing satellite formation configuration control main...
