Abstract

This paper shows the optimal placement method of distributed actuators for static deformation control in composite structures where the deformation of laminated plates is controlled using piezoelectric actuators bonded symmetrically to the laminate surfaces. The actuator locations are determined sequentially one by one so as to minimize the objective function which consists of the norms of the deformation and the actuator voltage. The optimal voltage for the specified actuator locations is obtained by the least squares method. The present method is verified by several numerical examples for laminated plates under various loading conditions.
