Abstract :
Parametric models for Permanent Magnet Synchronous Machines (PMSM) based on the magnetic coenergy function are presented. To characterise the nonlinear dependence on the stator currents, splines as piecewise polynomial functions are used. Also, a model of the utilised inverter considering error voltages due to the IGBT lock-time is shown. Two identification methods are described. Results of an identification of the parameters, extracted from measurement data, prove the validity of the models.
