Problems solved by technology

The A-axis rotates 360° at a constant speed within one orbital period. This installation method generally requires two A-axis and B-axis, and the configuration is complicated. In addition, under certain lighting conditions, the movement of the two wings of the solar wing will cause the entire star to suffer from severe gravity. Gradient moment disturbance, beyond the capability of satellite attitude control system

Description

technical field [0001] The invention relates to the field of satellite control. More specifically, it relates to a method for controlling a dual-axis solar wing drive mechanism of a low-earth inclined orbit satellite, a drive mechanism, a computer device, and a computer-readable storage medium. Background technique [0002] Satellites in orbit are in the light period most of the time. Solar cells are semiconductor devices that convert light energy into electrical energy. Solar cell arrays use solar cells to convert light energy into electrical energy through physical changes. It is currently the first choice for satellites. power generation device. According to the structural classification, solar cell arrays can be divided into two types: body-mounted and deployable. The solar cell array installed on the surface of the star structure is called a body-mounted solar cell array, and the solar cell array installed outside the star and unfolded and locked by a mechanism is cal...
