针对空间站交会调相过程中的长时间偏差传播问题,提出一种基于U变换的协方差分析方法 UTCAM。在给出空间站交会轨道调相策略和轨道机动参数计算方法后,对UTCAM的原理和流程进行了介绍,通过和STK以及Monte-Carlo的对比验证表明,UTCAM与该两种分析方法的协方差相对误差均在1.2%以内,且计算耗时仅为Monte-Carlo的1/460,可快速准确地实现非线性系统的均值和协方差预报。最后基于UTCAM对长达20天的空间站交会调相的偏差传播进行了分析,并采用Monte-Carlo仿真对其分析结果进行了验证,验证了该方法的有效性。

在推力器机动技术与零燃料机动(Zero Propellant Maneuver,ZPM)技术的基础上,提出了一种新的空间站大角度姿态机动技术概念——控制力矩陀螺辅助机动(Control Momentum Gyroscopes Assisting Maneuver,CMGs AM)技术。文章给出了CMGs AM燃料最优控制问题模型,在对燃料最优解控制结构分析的基础上,采用基于改进的伪谱结点法的求解策略,求解了CMGs AM燃料最优机动问题,与仅基于推力器机动的燃料最优解和空间站上的绕特征轴的常速率机动进行了比较,结果表明相对于推力器机动,CMGs AM技术更加节省燃料,并同时实现了机动始末动量管理模式的光滑连接;相对于ZPM机动,其机动时间大大缩短,同时具有更强的抵御干扰的能力。CMGs AM技术实现了对推力器技术与零燃料机动技术的高效综合,进一步丰富了空间站大角度机动技术。

目标航天器相位调整机动的目的是为交会对接任务做准备,是一个非固定时间交会问题。从调相的基本原理出发,分析了大气阻力、升交点赤经漂移及轨道误差对相位角的影响,并将这些参数用于改进冲量对相位角影响的估算公式。将估算公式与数值积分相结合,从摄动轨道机动参数计算、调相方向选取与机动圈次选择三个方面改进相位调整策略。仿真结果表明:提出的相位调整策略可以稳定高效地获得摄动轨道机动参数,能够满足终端精度要求,相对于直接根据相位角偏差正负来选择调相方向的策略可以节省推进剂消耗。
