| 摘 要： | 空间飞网是一种新型的空间碎片或漂浮物回收装置. 飞网抛射过程会对母体卫星产生较大的干扰,影响卫星的姿态稳定,因此需要设计具有抗干扰能力的控制律来保证卫星姿态的稳定. 针对空间飞网直接抛射展开过程,分析了影响飞网抛射效果的主要因素,并建立了飞网发射所产生的干扰力矩模型. 针对卫星的控制要求,建立了卫星姿态控制系统的模型,设计了滑模变结构控制器,并给出数学推导过程. 最后,通过仿真对姿态干扰及控制器控制性能进行了分析研究,结果表明,设计的控制器能够保证卫星的稳定,满足设计指标要求.

| Abstract: | Space net capturing is a novel technique for spacecraft capturing. In this paper, the disturbance imposed on the mother satellite, and the induced attitude control problem of the satellite, are investigated. Attention is focused on the dynamic process of mass ejection. The main factors affecting the performance of the net are analyzed and the model of the disturbance torque is developed. A sliding mode controller is developed to stabilize the attitude of the satellite and rigid mathematical proof is provided. Numerical simulation is conducted which demonstrates the effectiveness of the proposed algorithm. |
