Embodiment Construction

[0034] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0035] In order to better compensate the angular momentum and moment generated by the rotating load, the present invention utilizes a balance wheel to realize the compensation. In order to reduce the volume and weight of the balance wheel, it is equipped with small inertia rotating parts and works at high speed. The turntable is equipped with a large inertia load and works at a low speed, with strong maneuverability, which can better accurately and quickly track and match the balance wheel speed during operation.

[0036] The present invention firstly converts the given expected turntable operating speed of the satellite into the target speed of the balance wheel; the specific conversion formula is as follows: where J Z is the load inertia of the turntable; J P is the load inertia of the balance wheel; ω Z *The expected turntable operating...

Abstract

The invention belongs to the technical field of space-borne load application, and in particular relates to a method and system for compensating the angular momentum and moment of a space-borne large-inertia rotating load. To solve the problem that the existing compensation method cannot meet the load compensation requirements of large inertia and high speed, the system includes the first speed conversion unit, the balance wheel system, the second speed conversion unit and the turntable system; the method process is as follows: The speed is converted to the target speed of the balance wheel, and the balance wheel starts to accelerate to the target speed. The Hall signal output by the balance wheel is used to calculate the speed of the balance wheel in real time, and the real-time speed of the balance wheel is converted to the given speed of the turntable, and the reverse rotation is performed, thereby Ensure that the rotation speed of the turntable is matched and tracked with the rotation speed of the balance wheel in real time during the processes of acceleration, constant speed and deceleration to ensure the compensation effect of residual angular momentum and residual torque.

Description

technical field [0001] The invention belongs to the technical field of space-borne load application, and in particular relates to a method and system for compensating the angular momentum and torque of a space-borne large-inertia 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 devices, etc. The payloads of satellites vary with different missions. [0003] With the rapid development of satellite technology and the demand for satellite functions, the types of satellite loads show a trend of diversity. Some satellites carry large inertia rotating loads, which are generally carried on the turnta...
