编队飞行挠性航天器的输出反馈姿态协同控制

研究了在姿态调节和时变参考姿态跟踪情况下，且挠性模态变量和角速度不可测量时的编队飞行挠性航天器的姿态协同控制问题。针对姿态调节问题，在挠性模态不可测量的情况下，将文献中已有的用于刚体航天器编队飞行的比例〖CD*2〗微分协同控制器，推广到了挠性航天器编队的情形。然后，针对姿态跟踪问题，通过构造关于挠性模态的期望动态系统，并利用无源滤波器，提出了一种仅利用姿态测量信息的无速度反馈协同控制器。仿真结果表明了所提出控制方案的有效性。

Output feedback attitude coordination control of formation flying flexible spacecraft

The attitude coordination control problem for formation flying flexible spacecraft in the absence of the measurements of elastic modal variables and angular velocities,associated with attitude regulation and time-varying reference attitude tracking,is investigated.For attitude regulation case,an extension of a proportion-derivation(PD) coordination controller proposed by others for rigid spacecraft within formation to the case of flexible spacecraft is attempted in the absence of the measurements of elastic...
