This paper is concerned with the problem of suppressing the far-field acoustic pressure radiating from a structure interacting with fluid. In particular, it develops a modern control theory for the optimal control of the vibration of a submerged structure in a way that the farfield acoustic radiation pressure is minimized.

This paper develops a general modern control theory for the optimal control of the far-field acoustic pressure radiating from structures submerged in fluid. One difficulty in Refs. 14-16 is the selection of the modes to be controlled so as to minimize the far-field acoustic radiation pressure. Indeed, in Refs. 1 4-16 this selection is made by trial and error. 356
