Abstract

A good active noise control (ANC) system with online secondary path modeling should have the property that the operation of the ANC controller and the modeling of the secondary path are mutually independent. A new ANC system with online secondary path modeling is presented. Three cross-updated least mean square (LMS) adaptive filters are used to reduce mutual disturbances between the operation of the ANC controller and the modeling of the secondary path. Computer simulations have been conducted and the results show that the proposed method is able to produce superior performance compared to existing methods
