In many active noise control (ANC) applications, an online secondary pathmodelling method that uses a white noise as a training signal is required. This paperproposes a new feedback ANC system. Here we modified both the FxLMS and theVSS-LMS algorithms to raised noise attenuation and modelling accuracy for theoverall system. The proposed algorithm stops injection of the white noise at theoptimum point and reactivate the injection during the operation, if needed, tomaintain performance of the system. Preventing continuous injection of the whitenoise increases the performance of the proposed method significantly and makes itmore desirable for practical ANC systems. Computer simulation results shown inthis paper indicate effectiveness of the proposed method.
