Simulations of Loss Minimization Control Based on Motor Parameters for Indirect Field-oriented Control of Induction Motor

Abstract

This paper discusses a simulation of a loss minimizationalgorithm for induction motor drive. This algorithm, whichis based on motor parameters, varies the flux linkage to obtainthe lowest possible losses. Verification of the algorithm’s functionalitywas performed by simulations in MATLAB/SIMULINKenvironment. First, an induction machine model was built withthe parameters of a real motor, taking into account magnetic saturation,Joule losses in both windings, iron losses, and mechanicallosses. Then, simulations with indirect field-oriented control wereperformed. The simulations showed that there is an increase inefficiency in the low torque region.
