摘要： 1997年因"进步号"飞船与空间站对接时发生意外碰撞而使得姿态失去控制,从而导致太阳翼无法朝向太阳而获得能量。使用欧拉方法和四元数方法建立运动学方程,通过欧拉—庞卡莱方程建立动力学方程来分析其姿态恢复的运动过程,研究得出太阳翼能够重新得到光照的可行性方案。

Abstract: The Russian space station Mir suffered an unexpected collision when airship M-34 docked with it in1997.The kinematics equations established by methods of Euler and quaternion and the dynamics equations by Euler-poincare equations were applied to demonstrate the attitude maneuvers of Mir.An useful method by using thrust of Soyuz to make solar arrays illuminated by the sun obtained.Simulation results show that the method is effective and feasible.
