Abstract
A method and a device for controlling in closed-loop a final controlling element having integral action, in particular an injection-timing device of a high-pressure fuel pump. On the basis of a system deviation, an automatic controller defines a driving signal to be fed to the final controlling element. The output signal from the automatic controller is acted upon by a precontrol, which can be so specified that the final controlling element remains in its position.
