| Abstract: | The important effect of the error path on the performance of the system exists in the active noise control, and the adaptive algorithm is achieved through the transfer function of the error path. The adaptive modeling is applied to the error path of the system in this paper, then the process and the algorithm of the adaptive modeling are given. The results of simulation experiments indicate that the stability is improved and the attenuation level is increased and the convergence speed is faster for the system. |
