Abstract

The active noise control system using the strictly positive real property of the error model in the adaptive control theory has been proposed recently. However, this method is of no practical use because it has the assumption that the error path between the secondary source and the error sensor are known. In this paper, we present The convergence property of this method without the assumptions above. We make the convergence property clear by using the modified block diagram and the T'th order IIR filter expression. It is made clear that the disturbance preventing the estimation of filter coefficients varies with its probability. Consequently, we make it clear that the convergence property of this method has danger of divergence.
