摘要： 对于挠性梁收缩过程的不稳定性，提出了边界控制方案，并设计了相应的控制律。受控结构的振动能量总是被耗散，系统的阻尼被增强，从而挠性梁的伸展过程、收缩过程和平台保持过程都被稳定化。

Abstract: This paper deals with stabilization of a deployable/retractable flexible structure.A nonlinear boundary control scheme is proposed for the structure.It is proved that the vibration energy is dissipated and the damping is enhanced,thus the structure in the deploying,retracting and keeping phases is stabilized if the structure is under the control.
