A new robust DTC-SVM for high performance induction machine drives

The well-known direct torque control (DTC) is a very simple control method for inverter-fed AC drives, which characterized by fast dynamic response, structural simplicity, and low sensitivity to parameter changes. Attempts to combine DTC with SVM have led to new ways. This paper presents a new robust DTC-SVM for high performance induction machine drives. Simulation studies have been carried out for the proposed method and results are compared with traditional DTC-SVM. Simulation results show that the new scheme ensures good robustness and adaptability under modeling uncertainty and disturbances.
