时变结构的参数识别方法

METHODS OF TIME-VARYING STRUCTURAL PARAMETER IDENTIFICATION

较详细地叙述了时变结构参数识别方法在国内外的研究进展，指出了这一工作深入研究的理论与实际意义．对其中的典型研究成果，包括自动控制理论领域的研究成果，给出了简要介绍，叙述了将广义系统的识别方法用于结构系统的思路和问题，特别是在线识别技术和神经网络技术．介绍了使用小波理论来识别时变结构参数的新思想．最后简要地展望了这一领域的发展前景．

The methods of time-varying parameter identifications and some typical applications including autocontrol theory field are reviewed. The theoretical and practical aspects are discussed, specially the on-line identification technique and the neural net technique. The wavelet transform for time-varying modal parameter identification is also presented. Finally, some further research trends are pointed out.
