|Title:||Active Control Of Power Flow In Beams Using A Frequency Domain Adaptive Method|
|Abstract:||The advantages of controlling the active part of the power flow (structural intensity) are investigated using a simple example consisting of a beam with a quasi anechoic termination. A frequency domain feedforward adaptive filter using the steepest descent algorithm and an estimate of the gradient of the intensity divergence is implemented in a simulation environment. The simulation utilizes a model of a beam which was identified experimentally. It is shown that the control of structural intensity may produce a better attenuation of the overall vibration level compared to other methods. The proposed method can be extended for use in plates.|
