This paper deals with a study on the active structure-borne sound control of a flexible plate by the feedback control method. It involves modeling a real structure as a reduced-order lumped parameter model on the basis of modal analysis, and then adopting modern control theory to control the vibration of selected multimodes of a plate that has high radiation efficiency. The modeling procedure and the LQ and suboptimal control design are presented; control simulation of the discrete model is carried out in order to demonstrate the effectiveness of the method. Experimental work with vibration control of the plate enables a final verification.
