Nonlinear active noise control for headrest using virtual microphone control
چکیده انگلیسی

In this paper, a feed-forward nonlinear active noise control algorithm is developed using the Filtered-S LMS (FSLMS) algorithm and virtual microphone control for an active headrest application. Virtual microphone control is implemented to attenuate noise at the ears of the headrest occupant using the physical microphones placed at remote locations. The proposed nonlinear virtual microphone control algorithm is verified in real-time in a headrest. Different nonlinear noise processes are studied and it is shown that in all cases, the FSLMS algorithm outperforms the FXLMS algorithm in controlling nonlinear primary noise at a virtual location.


► The virtual microphone control algorithm is combined with nonlinear ANC algorithm.
► Paper on multi-channel nonlinear active noise control.
► Real-time results for an active headrest are shown to control nonlinear noise.
► Active control of the transformer noise as a nonlinear noise control is newly proposed.
