Active Noise Control for a One-dimensional Acoustic Duct Using Feedback Control Techniques: Modelling and Simulation
نویسنده
چکیده
The modelling and simulation of the Active Noise Control (ANC) using the fixed feedback control for a hard-wall one-dimensional acoustic duct system is discussed. The state-space models as well as the transfer function description are derived based on physical principles. The coupled dynamic between the cancelling loudspeaker and the acoustic duct is explicitly expressed in these models. Besides that, the basic and advanced ANC design problems can be formulated into a set of standard control problems. Simulation tests using a simple lag compensator show a bright potential of using feedback control techniques in the ANC design.

A High Performance Feedback Active Noise Control System
In many active noise control (ANC) applications, an online secondary path modelling method that uses a white noise as a training signal is required. This paper proposes a new feedback ANC system. Here we modified both the FxLMS and the VSS-LMS algorithms to raised noise attenuation and modelling accuracy for the overall system. The proposed algorithm stops injection of the white noise at the op...
