一种噪声与振动主动控制的滤波-MLMS算法

A FITERED-MEDIAN LMS ALGORITHM FOR ACTIVE CONTROL OF NOISE AND VIBRATION

滤波 -LMS算法在噪声与振动主动控制中最为常用 ,但在具有冲击干扰的环境下 ,其收敛性能变差 ,本文提出一种更具鲁棒性的滤波 -中值LMS算法 ,无论在冲击噪声还是在非冲击噪声环境下 ,都具有很好的收敛性 ,计算机仿真结果进一步验证了这种算法的有效性。

Filtered_LMS algorithm is most popular in active control of noise and vibration.Convergence performance of the algorithm is poor in impulsive disturbance encironment.A filtered_median LMS algorithm that is more robust to impulsive disturbance is proposed in the paper.If there is no impulsive disturbance,the two algorithms have the same convergence performance.Related conclusions are verified by computer simulation results.
