【摘要】 针对某三轴稳定小卫星,为了避免出现非太阳能电池平面对日自旋的极端情况,提出了一种基于磁力矩器控制的垂直消旋方法,配合使用反作用飞轮,共同完成小卫星的姿态控制任务。仿真结果表明,在无轨道数据情况下该垂直消旋方法优于单纯消旋方法,整体控制方案简单有效。即使在极端情况下也能保证电源系统的稳定供电,从总体设计角度提高了小卫星的可靠性。更多还原

【Abstract】 The micro-satellite attitude control was studied based on vertical damping,and a novel magnetorquer based vertical damping method was proposed for a certain three-axis stabilized micro-satellite to avoid the occurrence of the terrible situation that the non-solar-battery-plane spins towards the sun.In conjunction with reaction wheels,this method accomplished the satellite’s attitude control.The simulation results show that the vertical damping method outperforms the simple damping method when no orbit information is available,and the whole attitude control scheme is simple and effective.The proposed solution guarantees a stable power supply even under the extreme situation,and the reliability of the whole micro-satellite system.更多还原
