The major disadvantages of the conventional direct torque control (DTC) drive is the steady state ripples in torque and flux Using space vector control (SVM) method reduce the torque and stator flux ripples. In this paper, the use of SVM technique, a torque fuzzy controller is proposed to improve DTC performance and reduce significantly torque ripple. Simulation results will be presented and discussed...
A new direct torque control (DTC) strategy of induction motors based on double-fuzzy space vector modulation (SVM) was proposed. In conventional SVM-DTC, two PI controllers were used to generate reference voltage vector. The parameters of PI controller are difficult to determine. In order to improve away the disadvantages of conventional SVM-DTC system, flux and torque fuzzy controller were designed...
