Modeling of Active Noise Control Systems in Ducts
We analyzed the elements of the active noise control system in ventilation ducts. On the basis of this analysis we created a model of these elements. Specially we brought a model of the loudspeaker in the z-domain, suitable for description of systems containing analog and digital parts. Using such a model we are capable to analyze work and convergence of the adaptive signal processing algorithms applied to active noise control. As an example, we analyzed performance of FXLMS algorithm on simplified model of active noise control system in ventilation duct, and we have shown a strong influence of the loudspeakers transfer function on the power spectrum of the error signal.
