Abstract(in English)	Feedback active noise control (ANC) system which is effective for narrowband noise can get an input signal and monitor performance with only an error microphone. However, the feedback ANC system has a possibility of divergence because the disturbance of broadband noise such as background noise always corrupts the input signal for the system. In this paper, to surpress the disturbance, we propose a feedback ANC system using a linear prediction filter. Simulation results show that the proposed system is superior to the conventional system on the stability.
