Modeling and Analysis of Average Torque Control Strategy on Switched Reluctance Motor for E-mobility

Abstract

This paper investigates the Average Torque Control (ATC) approach for an electric scooter application using a 250W, Outer-rotor type, 8/6 Switched Reluctance Motor (SRM). It also employs a search algorithm based on a multi-objective function to determine optimum excitation angles to increase SRM drive performance. The MATLAB/Simulink environment is used to model and analyze the SRM drive control system. The simulation results demonstrate the drive system's smooth efficiency with reduced torque ripple over a speed range due to the optimum turn-on and turn-off angle selection. The ATC technique is selected as an ideal alternative for the SRM drive control system against other control strategies due to the wide-speed range application in an electric scooter. © 2021 IEEE.
