Design, Modeling, and Model-Free Control of Permanent Magnet-Assisted Synchronous Reluctance Motor for e-Vehicle Applications

Abstract

This paper describes the model-free control approaches for permanent magnet-assisted (PMa) synchronous reluctance motors (SynRMs) drive. The important improvement of the proposed control technique is the ability to determine the behavior of the state-variable system during both fixed-point and transient operations. The mathematical models of PMa-SynRM were firstly written in a straightforward linear model form to show the known and unknown parts. Before, the proposed controller, named here the intelligent proportional-integral (iPI), was applied as a control law to fix some unavoidable modeling errors and uncertainties of the motor. Lastly, a dSPACE control platform was used to realize the proposed control algorithm. A prototype 1-kW test bench based on a PMa-SynRM machine was designed and realized in the laboratory to test the studied control approach. The simulation using MATLAB/Simulink and experimental results revealed that the proposed control achieved excellent results under transient operating conditions for the motor drive’s cascaded control compared to traditional PI and model-based controls.

“…Versatile in application, PEMFCs are employed in diverse fields, including mobile devices, distributed power stations, and automobiles, with notable implementations in fuel cell or fuel cell-based hybrid vehicles like Mirai and Citaro, where the fuel cell-fed DC/AC traction drive system is used [9][10][11][12]. Rapid advancements have been made in advanced AC electric motor control algorithms in recent years, leading to a significant maturation of motor control strategies in these vehicles [12][13][14][15][16][17]. These developments in AC electric motor technology have been instrumental in enhancing the performance and efficiency of fuel cell or fuel cell-based hybrid vehicles, contributing to their increasing viability in the market.…”
