Abstract

Adaptive feedforward broadband vibration (or noise) compensation is currently used when an image of the disturbance is available. However in most of the systems there is a “positive” feedback coupling between the compensator system and the measurement of the image of the disturbances. The paper proposes a new algorithm taking in account this coupling effect and the corresponding analysis. The algorithm has been applied to an active vibration control (AVC) system and real time results are presented.
