Abstract :
In this paper, a dq model based on transformation theory for five-phase induction machines is presented. A detailed implementation of an indirect-type five-phase field-orientation control including the hysteresis-type pulsewidth modulation (PWM) current regulator is described. A method for continuous and disturbance-free operation of a five-phase field-oriented-controlled induction motor drive with complete loss of one, two, or even three legs of the inverter or motor phases is described. A complete analysis and computer simulation of this control technique is included
