COMPARATIVE ANALYSIS OF APPROXIMATE AND DYNAMIC MODEL OF FIVE PHASE INDUCTION MOTOR

In this paper, an approximate and dynamic modeling of five-phase induction motor is described in a step by step approach. Adq model based on transformation theory for five-phase induction machine is presented. A detailed implementation of an indirect-type five-phase field oriented control including the hysteresis-type pulse width modulation (PWM) current regulator is described for both approximate as well as for dynamic model. Simulations have been carried out for different load conditions. Simulation results verify that the performance of dynamic model is superior to approximate model.
