Abstract
This paper concerns the minimization of total acoustic power radiated from a vibrating planar structure using both active noise and vibration control with acoustic secondary sources and vibration control forces. First, the total acoustic power radiated from the model used in this paper is calculated using the reciprocity principle. And the optimal feed-forward control law for minimizing the total acoustic power is derived. Next, we show the phenomena under the optimal control condition, which are the control acoustic power becoming zero and the control vibration power also becoming zero. Finally, we show the control effects and the phenomena by using a specific example.
