Description: 有源噪声控制(ANC)主要基于LMS算法,但在处理宽带噪声信号和低信噪比情况下,效果不好.影响控制效果的主要原因是输入信号的自相关分布.而小波变换具有消除信号自相关的作用.因此将小波变换引入有源噪声控制(ANC)是解决问题的一种办法-Active noise control (ANC) is mainly based on the LMS algorithm, but ineffective in dealing with the situation of the broadband noise signal and low signal-to-noise ratio, the main reason affecting the control effect of autocorrelation distribution of the input signal. Wavelet transform to eliminate signalautocorrelation role Thus the wavelet transform is a problem-solving approach to the introduction of the active noise control (ANC) Platform: |

Description: 我提供了一个基于FXLMS的单通道前馈有源噪声控制系统的一个小例子.
为了减少噪声，我们使用控制器C（z）产生另一个“噪声”yw（k）。我们希望它破坏性地干扰X（k）。这意味着控制器必须是传播介质P（z）的模型。采用最小均方算法对控制器系数/权重进行调整。
然而，还有流体介质S（Z）留在致动器和传感器之间。我们称之为二次传播路径。所以，为了使解正确，我们需要用SH（z）来补偿调整过程，这是S（z）的估计(I provided him a little example of a single channel feed-forward active noise control system based on the FxLMS.
To reduce noise, we generate another 'noise' yw(k) using the controller C(z). We hope that it destructively interferes x(k). It means that the controller has to be a model of the propagation medium P(z). Least mean square algorithm is applied to adjust the controller coefficient/weight.
However, there is also fluid medium S(z) that stay between the actuator and sensor. We called it the secondary propagation path. So, to make the solusion right, we need to compensate the adjustment process using Sh(z), which is an estimate of S(z).) Platform: |

Description: This thesis introduces the basic research work on the development of the Narrowband Active Noise Control System (ANC). It focuses on providing the noise generator. It combines the virtual instruments’ hardware with software close to realize the function on three main parts: they are data acquisition, data analysis and extraction and noise sound generation, which is based on sound card for the A/D and D/A transformation. This system can not only be used to provide narrow band noise signal for the research of ANC, but also be widely applied to various fields such as diagnosing malfunction, spectrometric computation, signal source and so on.
