航天柔性结构振动控制的若干新进展

SOME ADVANCES IN THE VIBRATION CONTROL OF AEROSPACE FLEXIBLE STRUCTURES

围绕航天柔性结构的振动控制，从结构及材料的数学模型、材料及器件、基本理论与方法和一体化振动控制几个方面对一些研究的最新进展进行了介绍．主动控制和被动控制的一体化技术研究是当今航天柔性结构振动控制研究的重点，两种控制方法的结合不仅优点互补，而且提高了控制系统的性能．控制用材料和器件的研究在工程应用的推动下，也取得了较快的发展。

Some new advances in the research of mathematical models of structures and materials, materials and instruments, theories and methods, and integrated passive and active vibration controls are reviewed, with the focus on the vibration control of aerospace flexible structures. The integrated passive and active vibration is a research focal point of aerospace flexible structure vibration control. These two kinds of vibration control techniques have their respective advantayes and can be used to improve the performance of vibration control systems. Motivated by requirements from practical applications,the research on materials and instruments for vibration controls has also undergone a fast development and thus helped the practicability of vibration control techniques.
