Multi-Channel Hybrid Adaptive Noise Cancellation Compensating Nonlinear Distortions

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