Tlie control of a doubly-fed induction machine (DFM) with aid without tlie use of a rotor position encoder is examined. First, a stator fliix linkage oriented control scheme for power and speed control, with a position encoder, shows the high performance control capabilities of this control arrangement and serves as foundation for the sensorless scheme. The power-control method is then applied to a sensorless method, based on a previous control arrangement. This method is then exteiideci to
