Abstract
A new model of flexible plate (equipped with piezoelectric wafers) applicable for design and simulation of active control process is demonstrated. In particular, a concept of continuously distributed’active distortions’ describing interactions between piezoelectric wafers and the structure itself allows us to formulate properly the problem of optimal distribution for these control devices. The standard way to describe the interaction between piezoelectric devices and the controlled structure by means of concentrated forces applicable at the edge of actuator is not suitable to discuss the optimal location problem. Restricting control action to a chosen set of independently modificable eigenmodes of vibration and applying the criterion of maximization of available substitutive control action the discrete optimization problem can be finally formulated. A numerical procedure for solving this problem and corresponding testing example is presented.
