Résumé :

This paper presents the implementation of an instantaneous torque control technique named Direct Instantaneous Torque Control (DITC) on a 4-phase, 8/6, 30kW peak-power Switched Reluctance Machine (SRM) used for electric vehicle traction. On-line instantaneous torque estimation methods and the principles of the DITC are discussed. Simulation and experimental results are presented in the paper and a comparative study with current profiling techniques using three different torque-sharing functions is made. © 2012 IEEE.
