用MATLAB模拟盲源分离在结构损伤诊断中的应用

Application of blind source separation in structural damage diagnosis simulated by MATLAB

介绍了盲源分离的原理以及在大型结构损伤诊断之中的应用,在此基础上着重分析了其中运用很广泛的fast-ICA算法,涉及到了此算法的实现过程以及原理。并通过MTALAB对fast-ICA算法进行了仿真来证明其可行性和有效性,为以后应用于大型结构损伤诊断做好准备。

This paper introduces the principle of blind source separation and its application in large-scale structural damage detection,analyzes the fast-ICA algorithm which has a wide range use,and refers to the algorithm＇s princi- ple and realization. The feasibility and effectiveness of the fast-ICA algorithm are proved by using MATLAB simula- ting,which is prepared for later applied to large structural damage diagnosis.
