In this paper, we propose an online secondary path modeling ANC system using simultaneous perturbation method. This system updates the noise control filter by FXNLMS algorithm of fast convergence in case where the modeling error of the secondary path model is small. If the secondary path changes, the noise control filter is updated by the simultaneous perturbation (SP) method, which does not require the secondary path model and utilizes only error signal obtained at the error microphone, and the online secondary path modeling is conducted by using the perturbation components in the SP method. When the modeling of the secondary path is finished, the FXNLMS algorithm is applied to update the noise control filter by using the updated secondary path model again. Thus, the proposed online secondary path modeling ANC system can compensate the disadvantage of the FXNLMS algorithm for the secondary path changes based on the SP method. In this paper, we demonstrate the effectiveness of the proposed online secondary path modeling ANC system through some simulation results. |
