ELECTRICAL VEHICLE DRIVE CONTROL-BASED ON FINITE-ELEMENT INDUCTION-MOTOR MODEL

In this paper, the methodology for determination of an induction motor model including parameter variations for different operating conditio ns is presented. The method is based on finite elements and alternativ e techniques enabling to derive the equivalent circuit parameters from the field solution are described and discussed. The suitability of di fferent techniques for the consideration of time variations in the app lication considered, such as complex variables and time stepping techn iques, has been commented. The derived parameters are in good agreemen t with the low frequency response of the motor when supplied by a PWM inverter.
