Comparison by simulation of three-level induction motor torque control schemes for electric vehicle applications
This paper presents the results of an investigation into suitable torque control schemes for an electric vehicle application. The electric vehicle drive consists of rewound induction motors and a three-level IGBT inverter switching at 10kHz. The schemes investigated are Field Oriented Control, Direct Torque Control (DTC), DTC using Space Vector Modulation, and DTC with Minimal Torque Ripple. The results of Matlab- Simulink simulations and a comparison between the control schemes are presented. It is found that the DTC using Space Vector Modulation scheme is best for this application.
