Identification of rotor and stator flux linkage maps of squirrel cage induction motors based on identification of rotor time constant maps

Abstract

Model-predictive, field-oriented control of squirrel cage induction motors (SCIM) depends on the accurate identification and orientation of rotor and stator flux maps. In this paper, a new method is presented that utilizes the measured rotor time constant maps to reduce the orientation error of the identified flux maps. This enables the identification and modelling of the nonlinear and transient machine behavior, due to the estimation of the stator-and rotor-flux maps in dependence of stator and rotor currents.

Advanced Torque Control of Interior Permanent Magnet Motors for Electrical Hypercars

“…The IPM torque control needs flux LUTs on the d,q-axes, which means the resultant flux among the magnets' flux and the stator currents on the d-and q-axes for the optimal control, so, in the preliminary design phase, the FEMM analysis [14] is crucial for the performance evaluation in the Simscape model. Flux Linkage Maps identification is needed for the FEMM maps validation and the final experimental control implementation [15][16][17].…”
