METHOD FOR CONTROLLING A PIEZOELECTRIC ACTUATOR WHICH IS USED TO DISPLACE AN ELEMENT

摘要

The invention relates to the return stroke between an actuator and an element. In order to displace the element the actuator (A) is impinged upon by a control voltage (ANS). The control voltage (ANS) is selected in such a manner that it is dependent on the size of return stroke in order to compensate the alteration in the return stroke.
