| 摘 要： | 本文分析了LMS噪声抵消法的局限性,在讨论过程检测控制系统中信号和噪声一般模型的基础上,针对强噪声情况提出了一种基于建立相关模型的快速自适应滤波(FAF)。它是利用快速横向滤波(FTF)自适应算法对相关模型进行仿模而实现的。仿真与试验表明,本文所提出的方法较LMS法优越,适于过程检测控制系统采用。

| Abstract: | The limitation of LMS adaptive noise cancelling (ANC ) is analyzed here. Based on the discussing of general signal and noise model of process detection control system, a fast adaptive filtering(FAF) is proposed on the basis of modelling the correlativity between the noise and it's correlative noise with the view of large noise. Fast transversal filtering ( FTF ) adaptive, algorithms is used to imitate the correlative modelling. Both simulation and experiments show that the method presented in this paper is suitable for the process detection control system , and it exhibts better results than the LMS noise cancelling method. |
