Abstract

The invention discloses a configuration and control method for a satellite attitude control and large angular momentum compensation multiplexing flywheel. The configuration and control method comprises the following steps that a satellite pitch axis Y-axis is provided with a 25Nms angular momentum flywheel in a front mode, the positive angular momentum direction and the satellite body coordinate system+Y-axis direction are opposite, and offset momentum control is adopted in the satellite; the satellite yaw axis Z-axis is obliquely provided with two 50Nms angular momentum flywheels, the positive angular momentum direction is in the XOZ plane of the satellite body coordinate system and is separately biased towards the rolling axis+X-axis and rolling axis-X axis direction, and the angle between the positive angular momentum direction and the yaw axis Z-axis is 10 degrees; a satellite rolling axis X-axis is provided with a 25Nms momentum wheel in a front mode, the positive angular momentumdirection and satellite body coordinate system+X-axis direction are consistent; the flywheel rotation speed command is obtained by calculation, the control voltage command of the flywheels is obtained, the flywheels are driven, and the control angular momentum is output. The invention simultaneously completes the attitude control and the control output of the compensated angular momentum with a small number of flywheels.

Description

technical field [0001] The invention relates to a flywheel configuration and control method technology, and more specifically, to a configuration and control method of a satellite attitude control and large angular momentum compensation multiplexed flywheel. Background technique [0002] With the continuous development of aerospace technology, the development of satellite payloads has also shown multi-task and multi-functionalization. The antennas of the payloads are mostly rotating or the scanning mirrors are mostly swinging, which has achieved the purpose of dynamic and large-scale detection of targets. No matter the rotation of the antenna or the swing of the scanning mirror will generate interference torque, which will affect the stability of the whole star and affect the final imaging quality. [0003] In order to achieve high stability and high imaging quality for the whole satellite, the satellite platform needs the attitude and orbit control subsystem to compensate t...
