Abstract :This study presents a robust control system design for suppressing the radiated acoustic power emitted from a vibrating planar structure, and spillover effect caused by neglected high frequency modes. A state-space model of a simply supported plate is derived and an output equation is formed based on the one-dimensional PVDF film sensors. An output feedback H\infty control is designed by introducing a multiplicative perturbation which represents unmodeled high frequency dynamics in the control system. The simulation and experimental results are reasonable and show performance improvements.
