Title: Speed Performance of Direct Torque Control for Three Level Inverter fed Induction Motor: Sliding Mode Control Approach
Authors: T. Vamsee Kiran and J. Amarnath
Abstract: In recent years, the research has been focused to find out different solutions for the induction motor control having the features of precise and quick torque response and reduction of the complexity of field oriented algorithms. The direct torque control (DTC) technique has been recognized as the viable solution to achieve these requirements. The direct torque control of induction motors fed by two level inverter has certain drawbacks like more torque, flux and current ripples in steady state, which results in incorrect speed estimations. This paper presented the direct torque control of induction motor fed by a three level neutral point clamped inverter used in high power applications. To improve the speed performance of the drive against uncertainties caused by load disturbances, an integral switching surface sliding mode speed controller (SMC) is proposed. To validate the proposed method, simulation results are presented.
Keywords: Direct torque control, Sliding mode control, Neutral point clamped inverter.
