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 minimization algorithm for induction motor drive. This algorithm, which is based on motor parameters, varies the flux linkage to obtain the lowest possible losses. Verification of the algorithm's functionality was performed by simulations in MATLAB/SIMULINK environment. First, an induction machine model was built with the parameters of a real motor, taking into account magnetic saturation, Joule losses in both windings, iron losses, and mechanical losses. Then, simulations with indirect field-oriented control were performed. The simulations showed that there is an increase in efficiency in the low torque region.
