Abstract

In this paper, a control strategy of a Double Fed Induction Machine (DFIM) is proposed; this method is the most responsive drive in terms of speed variations. In this configuration two voltage inverters connected to the stator and to rotor windings are used which have enabled spreading out the power between the stator and the rotor thanks to their distribution and pulsation in motor operation mode. In this research, a Field Oriented Control (FOC) strategy is used in the DFIM to regulate the speed without a mechanical sensor. Subsequently, an Extended Kalman Filter (EKF) is designed to estimate the DFIM speed real-time and to replace with the sensor. Finally, the proposed sensorless control strategy is validated by using simulation tests and compared to the FOC based on a speed sensor. The results have shown the sensorless FOC strategy could improve the control robustness and system’s performance in case of a fault.
