A new fuzzy logic direct torque control scheme of induction motor for electrical vehicles application

摘要

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 10 kHz. The schemes investigated are Direct Torque Control DTC with three-level IGBT inverter, and a new direct-torque fuzzy control (DTFC) scheme of induction motor with space vector modulation (SVM) is presented. The results of Matlab- Simulink simulations and a comparison between the control schemes are presented. It is found that the DTFC and space vector application using three-level IGBT is best for this application.
