Application of the Fxlms Algorithm in Active Noise Reduction
Application of the filtered-X LMS algorithm to adaptive/active noise cancelling in headsets or hearing protectors has been investigated. The speed of convergence and amount of obtainable noise reduction was investigated for different step-size parameters and FIR filter lengths. Simple models for the headphone transfer function and the sound transmission through the ear cups are applied. We have...
متن کاملAn H 1 - Optimal Alternative to the FxLMS Algorithm 1
We study a general setting of active noise cancellation problems from the H1 point of view and present a solution that optimally limits the worst case energy gain from the interfering measurement errors, external disturbances, and initial condition uncertainty to the residual noise. The optimal bounding of this energy gain is the main characteristic of the proposed solution. To impose a nite im...
متن کاملOn use of averaging in FxLMS algorithm for single-channel feedforward ANC systems
In this paper an active noise control (ANC) algorithm is proposed. This algorithm is based on adaptive filtering with averaging (AFA) and uses a similar structure as that of the FxLMS ANC system. The proposed algorithm, which we call FxAFA algorithm, uses averages of both data and correction terms to find the updated values of the tap weights of the ANC controller. The computer simulations are ...
متن کاملA Disturbance Compensation Control for an Active Magnetic Bearing System by a Multiple FXLMS Algorithm
In this paper, a design technique is proposed for a disturbance feedforward compensation control to attenuate disturbance responses in an active magnetic bearing system, which is subject to base motion. To eliminate the sensitivity of model accuracy to disturbance responses, the proposed design technique is an experimental feedforward compensator, developed from an adaptive estimation, by means...
متن کاملActive Control of Chatter Vibrations in a Turning Process Using an Adaptive Fxlms Algorithm
In this paper a 2-DOF lumped mass model is used for dynamic modelling of a turning process. The cutting forces are modelled using predictive machining theory based on the Merchant cutting force model. Cutting parameters such as shear angle are calculated using experimental relations. Variation of cutting angles is also considered. Regarding the governing delayed differential equations, the mode...
