Hybrid Adaptive Noise Canceller Compensating Nonlinear Distortions

Abstract

A robust active noise controller is proposed to effectively linearize nonlinear distortions in the secondary path and be applied for attenuating the noise. In real applications, the overall active control system is nonlinear and the performance of noise attenuation is decreased by the extent of nonlinearities, so an active control system compensating nonlinear distortions is needed. Through computer simulations, the proposed controller had better capability of controlling the noises than the conventional LMS controller.
