航天器所需能源由太阳能帆板提供。针对单翼、单自由度、匀速驱动的太阳同步轨道卫星帆板的对日定向控制问题,研究了轨道偏心率、地球非球形摄动、日月引力、大气阻力、太阳光压等因素对卫星帆板对日定向精度的影响作用规律,为了提高对日帆板的定位控制精度,提出了在摄动影响下,采用线性拟合的方法,通过合理设置卫星帆板的驱动速度,延长卫星对日定向姿态的稳定时间。仿真结果表明,提出的方法简单易行,能够确保卫星帆板对日定向精度较长时间保持在允许范围内,在提高卫星帆板受晒效率的同时,减少了卫星帆板调整的次数。
The energy needed for spacecraft is provided by solar panels. Aiming at the orientation control problem of single-wing, single-degree-of-freedom and uniform-speed solar synchronous orbit satellite windsail, the effects of orbital eccentricity, non-spherical pendulum motion, solar gravitation, atmospheric resistance and solar pressure on satellite In order to improve the positioning accuracy of the windsurfing board, a linear fitting method is proposed under the influence of perturbation. By setting the driving speed of the satellite windsurfing board reasonably and extending the satellite pair Japanese orientation stance stability time. The simulation results show that the proposed method is simple and easy, which can ensure that the satellite windsurfing board can keep the orienting accuracy to Japan within the allowable range for a long time, and reduce the number of satellite windsurfing adjustments while improving the sunning efficiency of satellite windsurfing board.
