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-orientedcontrolled

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.
