Empirical Advancements in Field Oriented Control for Enhanced Induction Motor Performance in Electric Vehicle

Abstract

This paper introduces an advanced Field Oriented Control (FOC) strategy, specifically tailored for electric vehicle drivetrains, that streamlines the tuning process of PI controllers within the α and β coordinates of the synchronous reference frame. The innovative approach mitigates torque and stator current fluctuations while maintaining a constant switching frequency and improves inverter voltage use through third harmonic injection. Crucially, the theoretical underpinnings and simulation outcomes, obtained via MATLAB/Simulink, are substantiated by rigorous experimental verification. A dedicated DS1103-controlled testbed replicates real-world electric vehicle conditions, demonstrating the practical efficacy of the FOC method. The experimental results underscore the robustness of the control strategy across a broad range of operating scenarios, establishing a significant leap forward in electric vehicle control technology
