In the paper a new methody of on-line electro-acoustic plant model identification and update for adaptive multichannel feedforward ANC systems is presented. The proposed method uses external multivariate orthogonal multisine excitation added to the control signal. Properties of this excitation allow to decompose the overall multichannel identification problem into independent single-iput single-output identification problems. Additionally, special time-domain averaging of signals efficiently reduces an influence of disturbances on identification results even for low signal-to-noise ratio.
