N2 - In active noise control system, the filtered-X LMS algorithm is a frequently used algorithm. Before implementing the filtered-X LMS algorithm, the secondary path should be estimated in advanced. For time-varying circumstances, it is desirable to track the secondary path online. One common used online secondary path modeling technique is proposed by Eriksson, where an adaptive filter is induced to model the secondary path. The coefficients of the adaptive filter are updated by using LMS algorithm. Much work has been done to analyze the performance of the LMS algorithm in presence of disturbance. Almost all of them assume the disturbance signal is white noise. In this paper, the performance of LMS algorithm in presence of tonal disturbance is analyzed. The analysis is validated by simulations.
