| 摘 要： | 噪声主动控制技术是环境降噪的新技术,主动控制算法是其核心的问题之一。在研究滤波-X LMS主动控制算法基础上,提出了基于ⅡR滤波器的滤波-U LMS主动控制算法。对存在声反馈时的噪声主动控制中,可以提高系统的稳定性。设计了自适应主动噪声控制系统,对滤波-X LMS与滤波-U LMS主动控制算法进行了仿真和实验,结果表明,两种算法均能有效地应用于噪声主动自适应控制中,滤波-U LMS具有更好的宽频降噪效果。

| Abstract: | Active noise control is a new technology used in environment noise control.And adaptive control algorithm is the core principle of active noise control.Beside the study of fihered-X LMS algo- rithm,fihered-U LMS algorithm based on IIR filter is proposed which can improve the stability of the con- trol system while feedback noise is considered.An active control system is designed.Both the simulation and the test of fihered-X LMS and fihered-U LMS imply that,fihered-U LMS has a wider band of noise controlled. |
