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 conditions is presented. The method is based on finite elements and alternative techniques enabling derivation of the equivalent circuit parameters from the field solution are described and discussed. The suitability of different techniques for the consideration of time variations in the application considered, such as complex variables and time stepping techniques, has been commented upon. The derived parameters are in good agreement with the low frequency response of the motor when supplied by a PWM inverter.
