Sensorless motor control in application of electric vehicles
description Due to the advantages for the environment, the use of electric vehicles has been receiving more attention in the recent years. The motor control system is a crucial component of electric vehicle technology. Sensors have been utilized by motor control systems in the past to offer feedback on the position and speed of the motor. However, sensor-based control systems can be pricey, heavy, and prone to malfunction, particularly under harsh environmental conditions. As a result, sensorless motor control solutions for electric vehicles are gaining popularity. Without the use of physical sensors, sensorless motor control uses software and algorithms to determine the position and speed of the motor. This strategy can lower costs and complexity while enhancing reliability. The use of sensorless motor control in electric cars is the main topic of this report. The implementation of field-oriented control (FOC) approaches for sensorless motor control is specifically explored. With the use of a well tuned FOC, three type of observers will be designed to compare the esimated speed and position values observed, against the reference values.
