Abstract

A frequency mismatch (FM) compensation method is proposed for the narrowband active noise control (ANC) system to solve the problem of large nonstationary FM. Inspired by the momentum least mean square (LMS) theory, a new recursion algorithm for the updating of frequency compensation sequence is derived by incorporating a weighted accumulated square error into the cost function, and applied to the conventional filtered-X least mean square (FXLMS), filtered-X recursive least square (FXRLS), and variable step-size filtered -X LMS (VSS-FXLMS) algorithms, respectively. In both stationary and nonstationary environments, extensive simulations show that the proposed FM compensation method combined with the VSS-FXLMS based main controller possesses excellent tracking ability and is fast convergent.
