The invention discloses a sun control method under an analog sun sensor driving sailboard. The method comprises the following steps: determining the orientation of the sun relative to a satellite body; calculating a two-dimensional angle of satellite attitude control according to the azimuth of the sun relative to the satellite body; according to the two-dimensional angle, sun alignment of a satellite predetermined axis is achieved through flywheel control; determining a deviation angle delta theta between the current state of the sailboard and the ideal angle; and based on the deviation angle delta theta, driving the sailboard to rotate by utilizing the hysteresis control logic and the relationship between the sailboard drive and the deviation angle delta theta. According to the invention, after the sun appears on the analog sun sensor, the illumination condition of the sailboard can be maintained all the time.

    本发明公开了一种模拟式太阳敏感器驱动帆板下的对日控制方法,包括:确定太阳相对卫星本体的方位;根据太阳相对卫星本体的方位计算卫星姿态控制的两维角度;根据两维角度,由飞轮控制实现卫星预定轴的对日;确定帆板当前状态与理想角度之间的偏差角Δθ;基于偏差角Δθ,利用滞环控制逻辑和帆板驱动与偏差角Δθ之间的关系驱动帆板转动。本发明能够保证模拟式太阳敏感器出现太阳后,可以一直维持帆板的光照条件。
