Abstract

This paper deals with an active vibration control of a laminated composite plate with piezoelectric actuators/sensors under dynamic loading. PVDF films are used as a modal transducer for identifying specific modes in vibration measurement, and PZT actuators are used as actuators of vibration control. An optimal control law for each control mode is applied to the vibration control of a cantilevered laminated plate. Numerical simulation on vibration control is performed for a cantilevered laminated plate based on a finite element analysis incorporating the stiffness and mass effect of actuators. The effectiveness of the present methodology is verified by several numerical examples.
