Paper Abstract

A one dimensional theory is developed for modeling the analysis of beams containing piezoelectric sensors and actuators. The equation of motion and associated boundary conditions are derived for the vibrations of piezoelectrically sensored/actuated beams. The effect of coupling between longitudinal deflection and bending deflection is investigated in the present study. For the practical applications, in accordance with the proposed beam theory, a one-dimensional finite element formulation is presented. Based on the above one dimensional theory, an entire treatment of designing a state feedback control system for the piezoelectrically sensored/actuated beams is also presented. The results show the proposed approach has several advantages.
