A Comprehensive Analysis of Induction Motor Direct Torque Control For Electric Vehicle Applications

Road transportation is very crucial for socioeconomic growth because they empower cities and enterprises to operate globally. However, a significant portion of the transportation sector is dependent on reciprocating engines, causing an increase in greenhouse gas emissions and air contamination. Electric vehicles offer a viable solution to the transportation sector's problems. Control techniques such as direct torque control and indirect field-oriented control are frequently used. Most vehicles use DTC for controlling the induction motor due to its fast torque response and ease of implementation. However, DTC suffers from low switching frequency and high torque and flux ripples. Various improvements have been made to conventional DTC schemes to reduce ripple and improve performance. As a result, this article provides an overview of recent enhancements in DTC for induction motor control applied to an electric vehicle.
