Abstract

Focus is placed on the feedback (FB) active noise control (ANC) in order to reduce costs by simplifying ANC systems, because FB-ANC does not need reference signals. The purpose of this paper is to obtain a low order accurate model of an acoustic plant for FB-ANC and design a simple controller based on this model. The plant in this case is from the input to a single secondary loudspeaker to the output of a single error sensor (microphone). First, as a modeling method, physical modeling is applied. Second, Smith predictor is modified for FB-ANC to eliminate the influence of time delay in an acoustic field, and a PID controller is designed. Finally, effectiveness of the modeling methods and the proposed FB-ANC are demonstrated through numerical experiments using actual data.
