Paper Title:
Secondary Source Modeling Based on Analogue Circuits of Electrical Mechanical and Acoustical Systems
  Abstract

A method of secondary source modeling based on analogue circuits of electrical, mechanical and acoustical systems (SSM-ACEMAS) was provided in order to reduce the mismatch of transfer function estimation of secondary path in the simulation of active noise control (ANC) system. The convergence range and noise reduction performance of the system with SSM-ACEMAS and Filtered-X LMS algorithm were investigated. The results show that the transfer function of such a secondary source model has different amplitude and phase from the ideal model, which makes the noise reduction performance of an ANC system be much worse than the one with ideal model. Meantime, the convergence range of the control system is increased at low frequencies while decreased at high frequencies. The proposed model can provide a new method of secondary source modeling for further research on the simulation of active noise control system.
