挠性结构的分力合成主动振动抑制方法研究

针对当代航天器的大挠性特点和挠性附件的振动常影响航天器的姿态控制精度和指向精度的问题，全面分析了一种挠性结构的主动振动抑制方法－分力合成方法。分力合成方法的具体应用以若干个定理的形式加以总结。为了提高方法在工程实践中应用的可行性，又提出了改善方法对参数变动鲁棒性的定理并得到了严格的数学证明。数值仿真和地面试验进一步验证了该方法的有效性和简便性。

Study on Component Synthesis Active Vibration Suppression Methods for Flexible Structures

Considering the character of high flexibility and the problem in that flexible vibration usually affect the precision of attitude control and pointing of spacecraft, a kind of active vibration suppression method, component synthesis vibration suppression(CSVS) method, for flexible structures is completely analyzed in this paper. This detailed application of this method is given with several theorems. To improve the feasibility of CSVS method in engineering, the theorems of robustness to parameter variations are proposed and proved strictly. Numeric simulation and ground experiment validate the effectiveness and briefness of CSVS method.
