Abstract(in English) | This paper proposed a method to update the coefficients of feedback control filter using frequency domain simulataneous equations method under active noise control(ANC). This method doesn't require system identification for estimating the coefficients of feedback control filter and improves convergence speed. Because it is enabled that two equations can be estimate directly by extending the simultaneous equations method using linear prediction analysis in the frequency domain, In the beginning fo this paper, we derive theoretical equation of frequency domain simulataneous equations method. Next, we presents that coefficients of feedback control filter converge in high speed more by separating in primary noise and feedback noise by using two linear prediction filters. Further more, we presents the effectiveness of applying the frequency domain adaptive algorithm against colored noise. In the end, we study about the effect that give to the noise control the estimation error of the feedback control filter. |
