| Summary: | In this paper, the control of composite beam vibrations with sensor and actuator
connected layers is considered with consideration of the effect of thermal environment. The
coupling relation between electrical field and mechanical deformation with uncoupled thermal
impact are used. The mathematical model of shear deformation (Timoshenko’s theory) has
been applied and basic equations for piezoelectric sensors and actuators have been proposed.
The equation of motion for the beam structure is obtained by the Hamilton principle and
analyzed by finite element method. The control algorithm is based on proportional velocity
control. Hence, the purpose of this article is to investigate the direct and inverse effects of
piezoelectric on control of simply supported beam vibration under uniform temperature. |
