Apparatus for and method of actively controlling vibratory noise, and vehicle with active vibratory noise control apparatus

摘要

The filter coefficients of an adaptive notch filter are sequentially updated to minimize an error signal based on the error signal and a first reference signal which is produced by subtracting a signal which represents the product of a sine corrective value C 1 and a reference sine signal, from a signal which represents the product of a cosine corrective value C 0 and a reference cosine signal. The filter coefficients of an adaptive notch filter are sequentially updated to minimize the error signal based on the error signal and a second reference signal which is produced by adding a signal which represents the product of the reference sine signal and the cosine corrective value C 0 and a signal which represents the product of the reference cosine signal and the sine corrective value C 1 to each other.
