Abstract

Decoupled control has been widely used in the DIFG (doubly fed induction generator) which needs the rotor position as well as the rotor speed for the control system. A lot of research has been done in the sensorless control field for the DFIG because of the disadvantages of the speed sensor. Three representative sensorless control strategies are considered in this paper and they are compared in terms of their performances and speed tracking capability in different conditions.
