Abstract
A piezo valve is actuated by way of at least one actuator which is formed by a piezoelectric bender transducer () having two piezo actuators (). An actuating method has the steps of generating an actuator control signal (out), which can be output at either one of the two piezo actuators (), depending on at least one actuating control signal (in), of detecting an electric measurement quantity at one of the piezo actuators () which is currently not controlled (), and of generating a vibration damping signal (fb) on the basis of the detected measurement quantity and use thereof for active vibration damping for the currently controlled piezo actuator ().
