| Abstract(in English) | In this paper, we propose a method for detecting the convergence of the adaptive filter estimating the feedback path in feedback type active noise control systems. The estimation error necessary for effectively working the filtered-x algorithm is different from that required for sufficiently canncelling the feedback path. This indicate that two adptive filters are required for estimating the feedback path. In this paper, we propose a method for controlling the step size so as to be able to decrease the two estimation errors to less than the different two prescribed levels. |
