DISTRIBUTED PIEZOELECTRIC ELEMENT METHOD FOR VIBRATION CONTROL OF SMART PLATES

The Distributed Piezoelectric Element (DPE) method for active control of smart plates is presented in which the piezoelectric modal sensor and modal actuator are designed by means of cutting the entire piezoelectric layers into several independent elements. The modal coordinates and the modal velocities can be obtained from the charges and currents generated by the sensor elements, and the modalactuator is designed by modulating the spatial distribution of voltage applied on the piezoelectric actuator.
