摘要
针对传统的欧拉角方法不适用于航天器大幅度姿态机动运动的数值仿真 ,研究了用四元数表示的空间站伴随卫星的姿态控制问题。介绍了空间站伴随卫星的概念及任务 ;根据航天器动力学方程 ,利用李雅普诺夫直接法推导出用四元数表示的空间站伴随卫星姿态控制律 ,并对该控制律进行了仿真计算。仿真结果表明 ,所推导的控制律能对空间站伴随卫星进行准确。
The quaternion method is used to study the attitude control of accompanying satellites of space station in order to overcome the defects of traditional Euler technique, which is not applicable to numerical simulation of large attitude maneuver of spacecrafts. At first, the conception and task of an accompanying satellite of space station is introduced. Then, attitude control law of an accompanying satellite using Lyapunov function based on spacecraft dynamics is derived. Simulation result shows that the attitude control law can control the attitude effectively.
