Direct instantaneous torque control with wide operating range for switched reluctance motors

open access: yesIET Electric Power Applications, 2015
Owing to the constraint of the supply voltage, there is a theoretically maximum operating range of the smooth‐torque operation for a switched reluctance drive (SRD). The maximum operating range can be determined by the authors previous work, based on which a novel direct instantaneous torque control (DITC) is proposed for four‐phase 8/6 switched ...
