Abstract

The problem of antisymmetric non-stationary bending vibration control for round double-layered plate "metal-piezoceramic" is solved using Laplace integral transform. Control is carried out electrically, thus a configuration of the electric signal providing set behaviour of the normal to a surface of the plate in its center, is a subject of identification. The mathematical model of the plate is written within the theory of thin electroelastic shells. By the developed method the problem is reduced to the system of Volterra’s integral equations which is solved numerically using Tikhonov's regularization algorithm.
