Abstract This paper investigates the attitude maneuver problem of a spacecraft containing internal movable masses with zero angular momentum. The spacecraft dynamics in one dimension is first studied using the proposed moving mass control system with predefined mass motion. Next, a small-angle attitude maneuver method based on the sliding mode control technique is designed to accomplish the reorientation when the required maneuver angle is within the control capability of single-direction movable mass motion. Furthermore, a novel mass-shifting procedure is proposed for achieving full-domain attitude reorientation. The procedure includes a rest-to-rest maneuver method together with the trajectory optimization. Which, the rest-to-rest maneuver takes advantage of the attitude difference caused by sequential mass motion and the trajectory optimization is carried out based on time sub-optimal motion planning methods. The procedure is next combined with the small-angle maneuver method to achieve a high precision reorientation. Finally, numerical simulation results show that high precision full-domain attitude reorientation can be realized using the proposed control system with three internal movable masses.

使用可移动质量的卫星姿态机动

摘要 本文研究了包含零角动量内部可移动质量的航天器的姿态机动问题。首先使用具有预定义质量运动的拟议移动质量控制系统研究一维航天器动力学。其次，设计了一种基于滑模控制技术的小角度姿态机动方法，当所需的机动角度在单向可移动质量运动的控制能力范围内时，实现重新定向。此外，提出了一种新的质量转移程序来实现全域姿态重定向。该程序包括静止到静止机动方法以及轨迹优化。哪一个，rest-to-rest机动利用连续质量运动引起的姿态差异，基于时间次优运动规划方法进行轨迹优化。该程序接下来与小角度机动方法相结合，以实现高精度重新定向。最后，数值模拟结果表明，使用所提出的具有三个内部可移动质量的控制系统可以实现高精度的全域姿态重定向。
