Direct vector control strategy of 2-phase induction motor drives based on the conventional rotating transformation matrix and EKF
This research presents a novel mathematical model of 2-phase induction Motor (M 2 ) or star-connected 3-phase induction Motor (M 3 ) under the Open-Phase Fault (F OP ). In addition, a Direct Vector Control (DVC) strategy based on the Extended Kalman Filter (EKF) is proposed for M 2 drives. It is sho...

Zusammenfassung: | This research presents a novel mathematical model of 2-phase induction Motor (M
2
) or star-connected 3-phase induction Motor (M
3
) under the Open-Phase Fault (F
OP
). In addition, a Direct Vector Control (DVC) strategy based on the Extended Kalman Filter (EKF) is proposed for M
2
drives. It is shown that using the conventional rotating Transformation Matrix (TM), the mathematical model of the M
2
can be written as forward and backward quantities. Based on this modeling, a developed DVC strategy according to forcing the backward quantities equal to zero is achieved for M
2
drives. In the proposed DVC, an EKF is developed to estimate the rotor flux amplitude and angle. The proposed approach with minor modifications can be employed for both M
3
and M
2
drives. The experimental results on a star-connected M
3
test-bed with a DSP/TMS320F28335 indicate that the proposed EKF-based DVC (DVC
EKF
) method can precisely and effectively control the faulty M
3
drive during different conditions. The results also show that the proposed DVC
EKF
system has a better performance in comparison to conventional control systems during the F
OP
