Maximum Torque Control Operating Points Estimation for Variable-Speed IM Applications by Parameter-Based Model

Paper in proceeding, 2023

In this work, a follow-up study of estimating optimal operating points by an improved parameter-based model of three-phase induction machines (IMs) is conducted and presented. The main objective is to examine the representation of IMs' parameters within a specified operating boundary. The paper begins by reviewing the theory behind the inverse Gamma-form model (IGFM) and maximum torque control. This review serves as a foundation for developing methods for estimating operating points. Finally, the study compares the results obtained using a 2D electromagnetic finite element method (FEM) model of a 15kW IM with those derived using a parameter-based model obtained through the conventional method, demonstrating the practical utility of the improved parameter-based model.
