Simulation and Experimental Analysis for Active Vehicle Interior Noise Control Based on FFxLMS
摘要
Abstract
In view of the problems such as huge computational counts,low convergence speed and poor stability of the widely-used time-domain feedforward adaptive algorithm(TFxLMS)for active ve-hicle interior noise control,a FFxLMS was proposed based on fast Fourier transform(FFT)and block computation.The strengths and weaknesses of the FFxLMS algorithm and the TFxLMS algorithm were compared in terms of the noise reduction,computational count,convergence speed,and stabili-ty.Furthermore,the numerical findings were experimentally validated.The results show that the FFxLMS algorithm has advantages in noise reduction,computational count,convergence speed and stability.关键词
