摘要
把柔性附件简化为悬臂梁模型，用Ｈａｍｉｌｔｏｎ原理推导了附件伸展过程的时变系统动力学方程。强调了对伸展柔性附件进行振动抑制的必要性，由于系统的时变性，控制方法以主动控制为＊宜。应用ＬＱＲ理论设计反馈控制律，讨论了应用ＬＱＲ理论综合时变控制系统时参数的选取方法，数值仿真结果说明了方法是有效的。
The derivation of time-varying coefficient for dynamic equation of flexible appendagesduring extension is based on Hamilton principle. It is emphasized that it is necessary to applyactive control to damp out the vibration during extension and the theory of LQR is employed*to design the feedback control system. The method to select control system parametersfor synthesis of time-varying control system is discussed in detail. Finally numerical resultshows that the control system could work efficiently. *
