Abstract (in Japanese) (See Japanese page) 
(in English) In this paper,we propose an identification method of feedback path which occurs in active noise control systems.
In active noise control systems, if feedback path occurs,the sound emitted from the speaker is detected by the noise detection microphone,therefore it causes howling,and failure of a speaker.
To solve this problem,we use that we can calculate primary system and secondary system in simultaneous equations method.
In this paper,we present a method that we calculate the identification error of feedback path and feedback path control filter coefficient from that result,add the error to feedback path control filter coefficient,and finally verify the validity of them.
