| 摘 要： | 航天器三轴姿态控制常用的多飞轮控制方案中,反作用飞轮的单自由度动量交换属性使系统的功能重复部件和冗余件数目增多,严重影响了姿控系统的重量、体积、功耗及成本;由于原理和结构的限制,传统多自由度动量交换技术无法充分发挥其“多自由度”的固有优势,而新型多自由度动量交换技术的研究与发展则为这一优势的发挥提供了空间。本文综述了国内外多自由度动量交换技术研究的新进展,分析了其特点、关键技术和研究方向,并展望其应用前景。

| Abstract: | The character of one-degree of freedom of reaction wheel makes the amount of associated duplicated functional components and attendant redundancy increase in multi-wheel configuration for three-axis attitude control system,consequently the mass,volume,power and cost of attitude control system increase greatly.Compared with traditional momentum exchange technology,novel momentum exchange technology with multi-degree of freedom provides opportunity for developing the inherent advantage of "multi-degree of freedom".This paper summarizes the latest development of momentum exchange technology with multi-degree of freedom,analyzes its feature,key technologies,tendency of future research,and predicts application prospects. |
