Method for controlling a piezoelectric element or actuator based on a measure of quality of the oscillating behavior to provide a control parameter

摘要

The method for controlling the piezoelectric element (7) has a variable control parameter. To determine the control parameter, a quality value dependent on the control parameter, for the oscillating behavior of a condition parameter of the piezoelectric element to be controlled, is minimized. This measurement of quality can be, for example, the variation of the condition parameter to be controlled or an associated measured or estimated parameter.
