The most commonly used centralized adaptive strategy for that purpose is the multiple error FxLMS algorithm (MEFxLMS)  which is devoted to minimize the sum of the power of the N instantaneous error signals.

The minimization problem gives rise to the adaptation rule based on the FxLMS algorithm, which is expressed as:
After 5000 iterations, the adaptive filter updated by the FxLMS algorithm converged to the secondary path with error signal less than 0.01V.
This physical path, [P.sub.[phi]](z), is called the cancelation path; this transfer characteristics also affect the performance of the FxLMS algorithm.
The feedforward controller based on adaptive FxLMS algorithm is designed to attenuate the effects of the harmonic point-force disturbance on the ACLD/plate system in Figure 2.
The structure of the FxLMS
algorithm is shown in Figure 11, following the notation of 43].
The adaptive filtered feedforward FXLMS
algorithm is shown as follows:

Most of current ANC systems utilize the traditional filtered-x least mean square (FXLMS
) algorithm or its modified versions.
