【 摘 要 】

This paper studies the estimation problem of speed in a Doubly Fed Induction Machine (DFIM) controlled bya Field Oriented Control (FOC) Strategy. The DFIM is the most responsive in variable speed. The chosen configurationuses two voltage inverters connected to the stator and rotor windings, to adopt the power distribution between themthrough the pulses distribution of the stator and the rotor in motor operating mode. It is necessary to model the DFIMin three-phase equations and then in two-phase equations faithfully representing the characteristics of the machine.From this model, we can design and simulate the control. The control by oriented rotor flux can be realized by usingthe speed provided by sensors or estimators. In this paper, we have used the Extended Kalman Filter (EKF) in order toavoid problems caused by the motor speed sensor and improve the robustness of the control and its performancewithout using any speed sensor.
