Abstract
A method for the electric control of an actuator, especially a piezoelectric actuator of an injection system comprises the following steps: charging the actuator; waiting during a specific period of time (D, D) and discharging the actuator after the expiration of the period of time (D, D). The period of time (D, D) is variably determined in order to compensate the quantization steps.
