车内 ANC 系统次级通道辨识及仿真研究
Simulation Research on Secondary Path Identification of ANC System in Vehicle
摘要
Abstract
The algorithm of active noise control(ANC)system was deduced,and FxLMS algorithm was adopted as the control algorithm of the system to simulate. The two methods of secondary path identification were introduced,which are off-line identification method and on-line identification method. The advantages,disadvantages and adapted occasion of secondary path identification methods were analyzed. The additional random noise method which is noticed was selected to identify the secondary path,and the method can achieve the desired identification accuracy from the identification results. The ANC system was modeled and simulated by Matlab / Simulink. The simulation results show that the system can reduce the noise by above 15 dB commendably in the car.关键词
