Abstract

Die Erfindung betrifft ein Verfahren zum Bestimmen der Position eines Ankers, der einem Stellantrieb zugeordnet ist, wobei der Stellantrieb mindestens einen Elektromagneten mit mindestens einer Erregerspule aufweist, wobei der Anker zwischen einer ersten Anlagefläche an dem Elektromagneten und einer zweiten Anlagefläche bewegt wird und der Strom in und gegebenenfalls der Spannungsabfall an der wenigstens einen Erregerspule ermittelt wird, und der magnetische Fluss Φ durch die Erregerspule durch Integration der induzierten Spannung ermittelt wird, wobei die induzierte Spannung entweder berechnet wird aus dem Strom durch die Erregerspule unter Berücksichtigung des Betriebszustandes der Leistungsendstufe oder aus dem Strom durch die Erregerspule und dem Spannungsabfall an der Erregerspule ermittelt wird und dass die Wegposition durch ein Kennfeld oder eine Funktion, das bzw. die den Zusammenhang zwischen dem magnetischen Fluss Φ, dem Strom I und der Wegposition abbildet, ermittelt wird.
