| 摘 要： | 首先分析了具有Ｖｏｉｇｔ型粘性阻尼的挠性梁的动力学特性，构造了系统的有限维模态逼近模型，证明了其中Ｈ∞意义下的收敛性，进而构造了系统的低维控制规律，证明了闭环路控制的稳定性，从而形成了具有潜在工程应用前景的挠性空间结构振动控制的可靠方法。

| Abstract: | This paper mainly deals with low dimensional control of Flexible Space Structures (FSS). The key idea is to process the truncation and spillover of FSS system as a whole, which make it possible to control imfinite dimensional FSS system by low dimensional controller. To do so, the dynamic properties of FSS is analysed, and low dimensional approximation algorithm and low dimensional controller for FSS are constructed.Theoritical results denote that the algorithm proposed in this paper is effective in the vibration control of FSS system. |
