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 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
