编队飞行小卫星相对姿态控制研究

以四元数作为定位参数对编队飞行小卫星进行相对姿态控制。首先给出了以误差四元数作为反馈量 ,基于参考卫星的相对姿态控制律 ,其次 ,研究了由若干颗相同卫星组成的编队卫星 ,在卫星姿态达到指定的方位时 ,相互之间也要满足一定要求的相对姿态控制律。最后进行了仿真计算 ,说明了两种相对姿态控制的有效性和可行性

The Research of Relative Attitude Control on Small Satellite Formation Flying

In this paper, the quaternion is taken for positional parameters to relative attitude control of the small satellite formation flying. Firstly, using error quaternion as feedback, relative attitude control law, while reference satellite (space station) is the center in formation flying, is presented. The second case is that all satellites which form a large virtual satellite are both reference and adjoint satellites. When each satellite is in its goal orientation, the entire group of satellites is keeping relative attitude formation. Finally, typical example is given and the result shows that the method issued in this paper is effective and feasible.
