摘要

摘 要: 在介绍盲信号处理统一模型的基础上,全面归纳了其典型算法,综述了它在机械噪声监测与故障诊断中的研究现状,重点讨论了混合模型、噪声盲源分离与盲解卷积、盲源分离与多种技术的结合、噪声监测与诊断系统研究等方面的应用,并指出需要进一步研究的主要问题。

Abstract

Abstract: On the basis of introducing the unified model of blind signal processing (BSP), the typical BSP algorithms are comprehensively concluded, and the present research status of BSP in machine noise monitoring and fault diagnosis are summarized. It is emphatically discussed that mixed models, blind source separation and blind deconvolution of mechanical noise, blind source separation combined with other technologies and machine noise monitoring and diagnosis system based on BSP. Finally, the future further main research is put forward.
