In practical case of active noise control (ANC) system structure for the dual microphones, by the reference microphone and the error microphone composed. The reference microphone will pick up a signal from the feedback path of the ANC system, causing the acoustic feedback problem. In general the FxLMS algorithm does not consider the acoustic feedback compensation, thus reducing the active noise control system performance, worse case may make active noise control system becomes unstable. To solve the problem of acoustic feedback, we use literature proposed the concept of online feedback path identifying and applying an optimal variable step size algorithms for identifier and controller, used to online feedback path identification and the reference microphone the measured signals for acoustic feedback compensation, therefore improve the performance of active noise control system. For the system have a better performance, we add auxiliary noise power scheduling, used to identification signal decreases follow the error signal is reduced, identification signals to reduce the impact on performance, and improve overall performance. In the computer simulation are compared with existing methods that the proposed method has better performance.
