چکیده
Direct Torque Control using Multilevel Inverter (DTC-MLI) strategy has attracted a great deal of interest in recent years, in the field of high power induction machines or permanent magnet machines drives applications for high dynamic response. This proposal combines the advantages of the multilevel inverter with direct torque controlled based schemes. Numerous efforts have been accomplished for the improvement of classical DTC scheme mainly concentrating on power electronics, DTC controllers, flux and torque observers. Many new techniques have been successfully developed and applied not only for induction motors but also permanent magnet synchronous motors. This paper presents a survey on various topologies and control strategies used for DTC of multilevel inverter-fed induction motor. Several techniques and concepts are: switchingtable (Look-up table) based hysteresis DTC-MLI, DTC-MLI with space vector modulation, predictive control strategy of DTC-MLI and DTC-MLI with fuzzy logic controller.

متن کاملOn Line Determination of Optimal Hysteresis Band Amplitudes in Direct Torque Control of Induction Motor Drives
In conventional direct torque control (DTC) of induction machines, undesirable flux and torque ripples are produced. These occur since non of the selected inverter's voltage vectors are able to generate the exact voltage required to produce the desired changes in the electromagnetic torque and stator flux linkage in most of the switching instances. In addition, when direct torque control is imp...
