Tracking Performance of Active Noise Control System Using SSCF Adaptive Algorithm for Change of Acoustic Path

Abstract

In this paper, a tracking performance of the SSCF-ANC system for the change of the acoustic path is considered. It is known that the SSCF (Square Sum of Correlation Function) adaptive algorithm estimating the inverse transfer function of the unknown system is robust for the sound noise added at the input. The high tracking speed can be obtained with the inhibition of the adaptive control when a certain evaluation value is negative. The numerical verifications of the tracking performance of this system are also presented.
