Study about influence of power system operation and control of the piezoelectric actuators

Electronical power and control systems can decisively influence the performance of the piezoelectric engines and actuators. This paper presents the modeling of some ultrasonic motor and the role of some equipments that amplifies signals of variable frequency with the lower limit of 20 kHz and various wave forms, in order to obtain new performance in using the types of engines achieved in the Research Center EMAD from Stefan cel Mare University of Suceava and to identify new applications of the piezoelectric engines and actuators powered, controlled and monitored by the electronic systems achieved.
