| Abstract(in English) | In this paper, we propose an active noise control (ANC) system without the secondary path model. The proposed system is based on the frequency domain simultaneous perturbation optimization method we propose. Consequently, the coefficients of the adaptive filter in the proposed system are updated by only errccr signals. Since the conventional ANC system using the filtered-x algorithm needs the model of the secondary path between the secondary source and the error sensor, the ANC system becomes unstable by the modeling error. On the other hand, as the proposed ANC system doesn't need the model, the proposed system has an advantage not to become unstable by the model. Moreover, the proposed system converges faster than the conventional system using the time domain simultaneous perturbation optimization method. In this paper, we explain the principle and show the effectiveness on computer simulations. |
