Abstract

Offenbart werden ein Verfahren (1) zur sensorlosen Regelung einer fremderregten Synchronmaschine (11), welche einen Rotor aufweist, sowie eine Vorrichtung (10) zur Durchführung des Verfahrens (1). Das Verfahren (1) umfasst folgende Schritte: - Einspeisen (S1) eines Testsignals (M) auf eine Kenngröße eines den Rotor antreibenden elektrischen Stromes; - Messen (S2) der Kenngröße des den Rotor antreibenden elektrischen Stromes auf einer Achse eines die Synchronmaschine (11) beschreibenden Koordinatensystems; - Ermitteln (S3) eines FehlerSignals (p(T)) durch Korrelieren der gemessenen Kenngröße (x) des den Rotor antreibenden elektrischen Stromes mit einem zeitlich verzögerten Testsignal (m), welches aus dem eingespeisten Testsignal (M) ermittelt wird; - Anpassen (S4) eines Rotorwinkels (φ) als Reaktion auf das Fehlersignal (ρ(T)), falls das Fehlersignal (ρ(T)) einen Wert ungleich Null aufweist.
