The invention provides a large elliptical orbit solar array variable speed driving method. The method comprises the following steps: establishing a large elliptical orbit satellite and sun position relation model in a sun tracking attitude reference system; the solar array driving deviation of the large elliptical orbit satellite is defined according to the satellite and sun position relation model; and taking the solar array driving deviation as input of solar array driving control, determining a solar array variable-speed tracking control rule of the large elliptical orbit satellite, and implementing sun orientation of the solar array. By adopting the variable-speed driving method for the large elliptical orbit solar array, the variable-speed driving of the solar array is smooth, the stable tracking of the solar array to the sun can be ensured, and the influence on the attitude stability is also effectively reduced.
本发明提供了一种大椭圆轨道太阳阵变速驱动方法,包括:建立对日跟踪姿态基准系中大椭圆轨道卫星与太阳位置关系模型;根据卫星与太阳位置关系模型定义大椭圆轨道卫星的太阳阵驱动偏差;以太阳阵驱动偏差作为太阳阵驱动控制的输入,确定大椭圆轨道卫星的太阳阵变速跟踪控制规律,实施太阳阵对日定向。采用本发明大椭圆轨道太阳阵变速驱动方法,太阳阵变速驱动平缓,可以确保太阳阵对日稳定跟踪,也有效地减小了对姿态稳定的影响。
