Résumé

n this paper, a novel direct torque neuro-fuzzy control (DTCNF) scheme combining with space voltage modulation (SVM) technique of a three levels inverter is presented. Using neuro-fuzzy technique, the reference space voltage vector can be obtained dynamically in terms of torque error, sta- tor flux error and the angle of stator flux. Compared with conventional direct torque control (C_DTC), in this new technique, the ripples of both torque and flux are reduced remarkable, and switching fre- quency is maintained constant. Simulation results verify the validity of the proposed method. Keywords: Direct torque control, induction motor, neuro-fuzzy, space vector modulation, stator flux, three level inverter.
