| Abstract: | Based on the Lyapunov function and the stability condition of filter coefficients for the active controller,new algorithms applied to the single-channel and multi-channel active noise control are proposed.Computer simulations show that the performance of the new algorithms is better than the Filtered-X algorithms. |
