Abstract :
In this paper, a real-time Direct Field-Oriented Control (DFOC) is proposed for torque and flux control of electric vehicles powered by induction motors. DFOC is one of the most popular control strategies in the industry for induction motor drives and has the advantage to produce a continuous time control signal, helping to extend life of electric vehicle batteries; further, the Space Vector Modulation (SVM) improves torque, flux, and current steady-state performance by reducing the ripple. To estimate the rotor flux, a sliding mode observer is used. The experimental implementation in real-time of this control has been successfully done, used a 1/4 hp induction motor based on a dSPACE board. Results are presented to illustrate the advantages of this control scheme.
