Problems solved by technology

[0004] In addition, the solution of the prior art needs to install multiple sets of nozzles, the system is complicated, and there are more links such as pipeline joints, which lowers the reliability of the system as a whole.
[0005] Generally, the propellant components used in the attitude control nozzle and the main engine are not the same type, and multiple sets of propellant storage tanks and pressurized gas cylinders need to be installed. The structural installation space is tight, and the overall weight is relatively large.

Abstract

The present application discloses an attitude-orbit coupling control method and its system, wherein the attitude-orbit coupling control method includes: determining the orbital motion state; determining the attitude motion state; determining the attitude-rail coupling motion state according to the orbital motion state and the attitude motion state; Acquire the coupled motion relationship of attitude control and orbit control according to the coupled motion state of attitude and orbit, and issue control instructions according to the coupled motion relationship. The application has the technical effects of simplifying system design, improving system reliability and reducing system risk.

Description

technical field [0001] The present application relates to the field of aerospace technology, in particular to an attitude-orbit coupling control method and system thereof. Background technique [0002] At present, the orbit control and attitude control of the spacecraft adopt the decoupling control method. The orbit control adopts the main thrust engine that passes through the center of mass of the spacecraft, and the attitude control adopts a small thruster that does not pass through the center of mass of the spacecraft and only generates a moment around the center to generate a force couple. [0003] Specifically, such as figure 1 with 2 As shown, the attitude control uses three groups (6) attitude control nozzles 2 installed around the side wall of the vehicle body 1 for attitude control, the first attitude control nozzle 21, the fourth attitude control nozzle 24 or the third attitude control nozzle 21. The control nozzle 23 and the sixth attitude control nozzle 26 sim...
