Abstract

Transportation plays a vital role in societal progress, but its current reliance on finite and polluting fossil fuels necessitates a shift towards electric vehicles. This transition is crucial for reducing environmental damage and decreasing dependence on fossil fuels. Induction motors are widely favored in electric vehicles due to their durability and minimal maintenance requirements. Among various control techniques, Direct Torque Control (DTC) is recognized as the most efficient method for regulating induction motors in electric and hybrid vehicles. DTC accurately calculates flux, torque, and speed, resulting in faster response times and fewer machine settings. However, it does exhibit a drawback in the form of high torque ripples. To address this issue, the paper proposes a straightforward control strategy for three-phase induction motors that maintains performance while effectively mitigating torque ripples, utilizing techniques such as duty ratio control..
