利用转移矩阵进行姿态控制

传统欧拉角控制方法在处理大姿态角机动时往往出现奇异和交联问题。针对这一问题对欧拉角的跳变现象进行了讨论，并从飞行器实际姿态与需求姿态之间的空间关系入手，给出了一种消除欧拉角跳变现象的有效方法－转移矩阵法，仿真计算表明，该方法在大型航天器的姿态控制中可以有效地消除欧拉角奇异、交联和跳跃现象，在欧拉角跳变的情况下仍然能够实现对飞行器的控制。

The Utilization of Transition Matrix in Attitude Control

The traditional control method of Euler angle can't suit the case of large angle maneuvering control because of the phenomena of coupling and singularity. The phenomenon of Euler angle jumping is discussed in this paper. According to the three dimensional relationship between the factual attitude and the desire attitude, a method utilizing transition matrix is given for eliminating Euler angle jumping. The results of simulation show that the method is useful.
