Abstract (in Japanese) (See Japanese page) 
(in English) In this paper, we show that the continuation of secondary path estimation is essential for stably working noise control systems. Practically, the estimation error increases the difference between the optimum and the pseudo-optimum solutions, which consequently makes the noise control unstable. We show that the estimation error is random variable and the stability of the noise control cannot be not settled by only decreasing the estimation error. The stability is guaranteed on average by continuing the secondary path estimation.
