Feedforward Active Noise Control Systems with Improved Online Secondary-Path Modeling

摘要: This paper proposes a new method for feed- forward active noise control (ANC) systems with on- line secondary path modeling. The proposed 1) uses the same error signal updating noise- process as used modeling process, and 2) incorporates an averaging based flltered-reference al- gorithm in noise-control process. theoretical considerations are conflrmed by computer simulations, which show that achieves better performance than existing methods. improved is achieved at expense of slightly in- creased computational complexity.
