Combined magnetising flux oriented control of the cascaded doubly-fed induction machine

摘要

A cascaded doubly-fed induction machine (CDFM) is a connection of two wound rotor induction machines. In comparison to a single doubly-fed (wound rotor) induction machine (SDFM) brushes are obsolete. Because of recent developments in brushless doubly-fed machine design, there is a renewed interest in associated control.
