Abstract
The present investigation concerns control of far-field acoustic radia tion generated by a thin plate in a broad frequency band using piezoel ectric films. System dynamics is of modal nature. This paper describes a comparison of numerical and experimental results for a closed loop type control. This comes from Optimal Control Theory via radiation fil ter causal transformation based on a dissipative criterion.
