Modelling and Control of Permanent-Magnet-Assisted Synchronous Reluctance Motor for Enhanced Performance in Electric Vehicles

Abstract

This paper propose an advanced control system for  permanent-magnet-assisted synchronous reluctance motor (PMaSynRM) for electric vehicles. The enhanced design aims to improve the dynamic response and operational stability of the motor, crucial for optimizing performance in electric vehicle applications. We introduce a comprehensive control framework that includes proportional-integral (PI) controllers for the inner loop focusing on current control, and a sophisticated outer loop controller designed to manage speed and torque seamlessly. Simulation results demonstrate the effectiveness of the dual-loop control in maintaining high efficiency and minimal torque ripple under varying load conditions. This integration not only refines motor performance but also ensures robustness and reliability, achieving an overall system efficiency of 95%. The study provides a detailed analysis of the modeling and control strategy implementation, its impact on motor performance, and the associated enhancements in efficiency and torque handling capabilities.
