Effekte zeitdiskreter Ansteuerung von Asynchronmaschinen bei hohen Drehzahlen

ZusammenfassungDie zeitliche Diskretisierung der Statorspannungen beim Betrieb einer umrichtergespeisten Asynchronmaschine bewirkt eine Verkopplung des d- und des q-Zweiges im Rotorflusskoordinatensystem sowie störende Stromrippeln. Dies führt bei der Regelung und bei der Schätzung des Rotorflusses zu Problemen. Dieser Beitrag stellt eine eingangs- wie auch ausgangsseitige modellgestützte Kompensation dieses Effekts vor.AbstractWhen controlling an induction machine, the stator voltage vector is discretized temporally. This leads to cross-coupling in the rotor flux frame as well as to current ripples, deteriorating flux control and estimation performance. This article presents both input and output compensation methods for this effect.
