چکیده
This paper proposes an improved performance cross-updating active noise system with online secondarypath modeling. The existing cross-updating active noise control system comprises three adaptive filters; a noise-control filter, a secondary-path modeling filter, and an adaptive-noisecancelation filter; where FxLMS algorithm is used in adaptation of the noise-control filter. In the proposed method, on the other hand, the noise-control filter is updated using modified FxLMS (MFxLMS) algorithm. Simulation results show that the proposed method gives better performance than the FxLMS algorithm based cross-updated ANC system.

An Optimized Online Secondary Path Modeling Method for Single-Channel Feedback ANC Systems
This paper proposes a new method for online secondary path modeling in feedback active noise control (ANC) systems. In practical cases, the secondary path is usually time-varying. For these cases, online modeling of secondary path is required to ensure convergence of the system. In literature the secondary path estimation is usually performed offline, prior to online modeling, where in the prop...

متن کاملA High Performance Feedback Active Noise Control System
In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...

متن کاملActive noise control without secondary path modelling – Fx-LMS with step size sign and value updated using the artificial intelligence
The Filtered-x LMS algorithm, when applied to active noise control, uses a secondary path model in order to update control filter parameters. The model is, however, subject to an error if the plant changes, what can result in algorithm divergence. Additional excitation signal can be then used to update the model on-line. Active control system properties are also dependant on the algorithm step ...
