Feed-forward active noise controllers with on-line tuning are designed for acoustic ducts in this thesis. A hybrid system identification technique is first utilized to establish a model that includes dynamics of one-dimensional sound field and associated actuating subsystems. Base on this model, we design a feed-forward active noise controller by using a model matching technique. An on-line tuning feed-forward active noise controller is then obtained by combining this designed feed-forward active noise controller with an adaptive FIR filter using filtered-X LMS algorithms. Both computer simulations and experiments are carried out to demonstrate broadband noise reduction performance of the proposed approach.
