摘要： 针对载荷转动对星体产生的呈周期变化的干扰，开展了干扰抑制方法研究。利用干扰的周期特性，基于李亚普诺夫原理设计了参数未知的周期干扰力矩的辨识算法，实现了卫星姿态的自适应控制。最后进行了物理仿真试验，利用真实的星载计算机和控制部件，在气浮台上进行了试验验证，结果表明,算法有效地抑制了载荷转动的干扰，卫星的姿态稳定度提高了50%，且算法简单，易于星上软件实现。

Abstract: The interference suppression method was studied for the periodic change of the satellite generated by the rotation of the load. Using the theory of Lyapunov stability, an adaptive control algorithm based on parameter identification for periodic signal was proposed. And then physical experiment verification using real onorbit computer and control components was carried out．The results show that the method proposed is in effect, improving satellite stability by fifty percent, and is easy to realize.
