A ROBUST FEEDBACK CONTROLLER IMPLEMENTATION FOR FLOW INDUCED STRUCTURAL RADIATION OF SOUND

摘要

This work has shown that a practical robust feedback controller implementation for the flow inducedstructural radiation of sound problem is possible. The robust controller design incorporatesuncertainty to ensure stability and it avoids saturation of the control transducer. Significant soundpressure level reductions were obtained at the odd-odd resonances. The controller achieved performanceusing a small controller DC gain and low order. This result is obtained as a directconsequence of the ability of the design method to utilize beneficial plant characteristics.
