摘要：An piezo actuator loading signal is determined and generated according to anoutput value and a pilot control value which depends on at least one operationalparameter. The loading signal causes that a valve member moves into a valve seat. A first
value characteristic of the electric power fed to the actuator when the valve member hitsthe valve seat is determined while a second value characteristic of the energy deliveredto the actuator is determined when the loading process of the actuator has beencompleted. A real value characteristic of a sealing force with which the valve member ispressed onto the valve seat is determined according to the first and second value. Thereal value and a predefined setpoint value are fed to the controller which accordinglyadjusts a pilot control value assignment instruction which is used for determining thepilot control value if a predefined condition is met.
