Abstract :
This paper presents a new methodology for feedforward filter design in active noise cancellation in the presence of acoustic coupling. This is done via a feedforward filter estimation that uses a dual-Youla parametrization to incorporate the acoustic coupling. The experimental results show that the feedforward filter parametrized and estimated via dual-Youla parametrization provides an effective feedforward compensation for the active noise control in an airduct.
