文章进行了冗余轮系航天器角动量包络分析及角动量管理问题研究.基于轮系可视化角动量包络分析,提出了一种角动量包络特征参量描述及基于特征参量的沿任意方向飞轮极限角动量的解算方法,并设计了一种基于以飞轮极限角动量为参考的零运动力矩分配轮系角动量管理策略,该方法充分利用轮系最大角动量容量,以避免系统角动量未达到包络面时出现部分飞轮角动量饱和的现象,数学仿真对比验证了所提出策略的有效性.
In this paper, the angular momentum envelopment analysis and angular momentum management of redundant gear trains spacecraft are studied.According to the visual angular momentum envelope analysis of train wheels, an angular momentum envelope characteristic parameter description and a method based on eigenvalues A method of solving angular moment of flywheel limit angular momentum is proposed and a method for managing angular moment of zero moment torque distribution system based on flywheel limit angular momentum is designed. This method makes full use of the maximum angular momentum capacity of the wheel system to avoid the system angular momentum Saturation of some flywheel angular momentum occurs when the envelope surface is not reached, and the simulation results verify the effectiveness of the proposed strategy.
