FLUX OFFSET COMPENSATION FOR A ROTATING ELECTRICAL MACHINE

A method is provided for compensating the flux drift caused by measurement and/or calculation errors when controlling a rotating electrical machine. The flux drift of the estimated flux vector may be compensated for by comparing the length of the flux vector with a reference flux magnitude which alr...

Beschreibung
Zusammenfassung:	A method is provided for compensating the flux drift caused by measurement and/or calculation errors when controlling a rotating electrical machine. The flux drift of the estimated flux vector may be compensated for by comparing the length of the flux vector with a reference flux magnitude which already has been determined for controlling the inverter. Depending on the comparison, the length of the estimated flux vector may be lengthened or shortened.
