In this work, we address the problem of pull-out and stalling of the vector control of the piezo-actuator drive (PAD). The model presented reveals the similarities with synchronous machine and therefore we propose the vector control to solve the problem and to enhance its performances. The implementation using a position sensor is tested. Experimental results show that the vector control avoids pull-out and reduces dramatically the voltage applied to achieve the same performances. Speed up to 2.5 times the maximum rated speed at full load could be achieved without loss of synchronization.

Stress in a piezoelectric material can be controlled by imposing an electrical field. Thanks to feedback, this electrical field can be a function of some strain-related measurement so as to confer on the piezoelectric ... -

The multimodal control of a 2D controlled-Friction Device is presented. We use the Vector control method because the phase and amplitude of two vibration modes at a same frequency can be precisely set. The closed loop ...

When the frequency of the source of vibration of a piezolectric generator is significantly different from its eigenfrequency, the dielectric power losses become prominent and decrease the amount of power which is practically ...
