Robust and Adaptive Feedback Noise Attenuation in Ducts
IEEE Transactions on Control Systems Technology
In this paper the attenuation of sound propagation in an air-handling duct using robust and adaptive feedback active noise control strategies is investigated. The case of multiple narrow band disturbances located in distinct frequency regions and the interference occurring in the presence of disturbances with very close frequencies are considered. The active control uses a loudspeaker as compensatory system. The objective is to minimize the residual noise at the end of the duct segmentdoi:10.1109/tcst.2017.2779111 fatcat:fxsbnpkttvhxrpg7zxcnvabihu
