Direct torque control of five-leg inverter-dual induction motor powertrain for electric vehicles

Direct torque control of five-leg inverter-dual induction motor powertrain for electric vehicles This paper deals with the adaptation and implementation of an adaptive direct torque control for the five-leg inverter-dual induction machine drive. The expectations are to take advantage of the direct control benefits, which are: sensorless, ease of implementation, and robustness against parameters variation. The application focuses on an electric vehicle with two driving wheels. For this, both induction motors coupled to the driving wheel are fed through a five-leg power inverter. For that purpose, the structure of this vehicle requires an electric differential, which allows maintaining the stability of the vehicle and especially during cornering. For this, the proposed direct control can ensure the separate control and distribute the required torques to the induction motors. Experiments and simulations are carried out to show that the developed independent control of five-leg inverter is effective and provides a simple configuration with good performance in terms of speed and torque responses. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Electrical Engineering (Archiv fur Elektrotechnik) Springer Journals

Abstract

This paper deals with the adaptation and implementation of an adaptive direct torque control for the five-leg inverter-dual induction machine drive. The expectations are to take advantage of the direct control benefits, which are: sensorless, ease of implementation, and robustness against parameters variation. The application focuses on an electric vehicle with two driving wheels. For this, both induction motors coupled to the driving wheel are fed through a five-leg power inverter. For that purpose, the structure of this vehicle requires an electric differential, which allows maintaining the stability of the vehicle and especially during cornering. For this, the proposed direct control can ensure the separate control and distribute the required torques to the induction motors. Experiments and simulations are carried out to show that the developed independent control of five-leg inverter is effective and provides a simple configuration with good performance in terms of speed and torque responses.
