| Abstract(in English) | This paper derives a frequency domain simultaneous equations method that can automatically recover the noise reduction effect degraded by secondary path change. Differently from the filtered-x algorithm, this method does not require the secondary path filter for estimating the coefficients of noise control filter, instead, exploits the estimation errors involved in the coefficients ; thereby yields two independent equations giving the primary and the secondary paths as unknowns. By solving these two independent equations, this method directly estimates the noise control filter coefficients minimizing the error sensor output. This paper presents a simulation result to confirm whether this method reduces a noise of diesel generator. Thereby, the availability of this method is confirmed. |
