Maximum Torque Per Watt (MTPW) field-oriented control of induction motor

Abstract A new field-oriented control strategy for induction motor is proposed in the paper. It called Maximum Torque Per Watt (MTPW) and allows obtaining minimum value of sum stator rotor losses due to joule effect, iron losses, a given reference torque speed. Iron have been modeled according Steinmetz equation, separating hysteresis eddy currents taking into account dependence both on frequency peak flux density. Numerical experimental results are presented confirm validity approach, which achieving significant improvements efficiency drive.
