| 摘要: |
| 为研究三轴跟踪平台的过顶问题，讨论了退化α型跟踪算法，提出了完全退化型算法和三步跟踪算法，并从理论上证明了所给出的算法可以解决过顶问题。对距离地球表面大约2000km星体，应用完全退化型算法进行计算机观测仿真，计算数据表明，运用完全退化型算法可以使三轴的转动角速度控制在0.56((°)s)以内。随后将三步跟踪算法应用到三轴自动跟踪平台试验，试验表明三步跟踪算法可以解决过顶跟踪问题。 |

| Abstract: |
| In order to study a three-axis overhead tracking problems, α-degenerative tracking algorithm is discussed. A completely degenerate tracking and a three-step tracking algorithm are proposed. It is proved theoretically that they can solve overhead tracking problems. Furthermore, by applying the first algorithm, it is simulated that the three-axis tracks to a satellite orbits abou 2000km form the Earth. The simulating data shows that the completely degenerate algorithm keeps the rotation speed of each axis within 0.56 degrees per second. The second tracking algorithm is used in the three-axis automatic tracking experiment. It shows that the three-step tracking can solve the overhead tracking problem. |
