New filtered-x recursive least square algorithm for active noise control
نویسندگان
چکیده
A new multichannel filtered-x recursive least square algorithm for active noise control systems is proposed. It is shown that the use of the filtered-x structure, instead of the commonly used modified filtered-x structure lead to a more efficient implementation and similar convergence performance and stability. The paper is also focused on examining the benefits of auxiliary normal equations solving methods needed by the formulation of the RLS problem. The behavior of the proposed algorithm is investigated in cases of ideal and nonideal acoustic plants.

متن کاملA Filtered-X RLS Algorithm for Nonlinear Active Noise Control
In this paper, a filtered-x recursive least squares (FX-RLS) algorithm based on adaptive 3rd-order Volterra filtering is proposed for nonlinear active noise control (ANC) of systems with a nonlinear primary acoustic path. The simulation results show that the proposed approach yields faster convergence, compared with the conventional methods (e.g., FX-NLMS and FX-GSPAP), for the nonlinear ANC. K...
متن کاملConstraint filtered-x and filtered-u least-mean-square algorithms for the active control of noise in ducts
In the active control of noise in ducts, it is common practice to locate an error microphone far from the control source to avoid the near-field effects by evanescent waves. Such a distance between the control source and the error microphone makes a certain level of time delay inevitable and, hence, may yield undesirable ffects on the convergence properties of control algorithms such as filtere...
