Tóm tắt
This paper proposes an efficient extension of functional links artificial neural
networks (EE-FLANN) for the active noise control (ANC) application. The
developed EE-FLANN controller can upgrade the model accuracy with the
actual system thanks to adding the cross-terms to the trigonometric function.
Unlike the method in the generalized FLANN (GFLANN) controller, the
EE-FLANN exploits include cross-term symmetry. However, this causes the
computational burden to increase remarkably. To reduce this disadvantage,
we truncate the cross-terms appropriately based on the simplified strategy.
Furthermore, the adaptive algorithm is designed to partially update the filter
coefficients appropriately. Specifically, the cross-terms that do not satisfy
certain magnitude conditions will be omitted during the update process to
reduce costs. Experiments have shown that the proposed EE-FLANN
controller can achieve comparable performance to the GFLANN controller
but the complexity is reduced by up to 20%
