Problems solved by technology

[0004] Compared with traditional satellites, satellites with large inertia rotating loads have static unbalance, which is caused by the deviation of the center of mass of the rotating load and the center of mass of the satellite body from the axis of rotation; the static unbalance leads to dynamic coupling between the rotating load and the satellite body effect, which affects the attitude stability of the satellite, and cannot meet the requirements of the payload for attitude control accuracy and stability

Abstract

The embodiment of the invention discloses an attitude control method of a satellite platform with rotary loads. The method includes the steps of measuring relative movement parameters of the rotary loads relative to a satellite platform, inputting the relative movement parameters to a preset static unbalance disturbance torque model to obtain the static unbalance disturbance torque of the rotary load acting on the satellite platform, and controlling the attitude of the satellite platform according to the static unbalance disturbance torque. The embodiment of the invention further discloses anattitude control device of the satellite platform with the rotary loads, a storage medium and an information processing device.

Description

technical field [0001] The invention relates to the aerospace field, in particular to an attitude control method and device for a satellite platform with a rotating load. Background technique [0002] The payload of the satellite bears the tasks and missions of the entire satellite. The payload of the satellite involves multiple fields such as optics, radio, and microwave, and undertakes various tasks including ground imaging, communication, resource survey, and meteorological observation. Common payloads include infrared scanners, synthetic aperture radars, visible light charge-coupled device (CCD, Charge Coupled Device) cameras, etc. The payloads of satellites vary with different tasks. [0003] With the rapid development of satellite technology and the demand for satellite functions, the types of satellite loads are showing a trend of diversification. Some satellites need to perform scanning operations due to mission requirements, and carry large inertia rotating loads. ...
