Abstract :
In this paper, we propose a feedback active noise control (ANC) system including a linear prediction filter. The proposed ANC system can reduce narrowband noise while suppressing disturbance having broadband components. The disturbance makes the conventional feedback ANC system unstable or divergent because the disturbance corrupts the input signal to the system. In the proposed ANC system, a linear prediction filter is combined with the feedback ANC system in order to suppress the disturbance. Simulation results demonstrate that the proposed feedback ANC system is superior to the conventional feedback ANC system on the stability while maintaining the same noise reduction ability.
