Control method for a piezoelectric actuator and corresponding actuator

摘要

A required voltage for a desired deflection of the piezoactuator (12) is determined by the deflection characteristic curve of the piezoactuator. The voltage of the piezoactuator while being supplied with current, is measured. The current supply to the piezoactuator is stopped when the measured voltage corresponds to the required voltage. An Independent claim is also included for piezoelectric drive.
