Field Oriented Control of Brushless Direct Current Motor for Electric Vehicle Robot Obstacle Detection and Avoidance

Abstract

This paper presents an approach to implement Field Oriented Control (FOC) brushless directcurrent motor using PID Controller for electric vehicle obstacle detection and avoidance. A state spacemodel of the BLDC motor with FOC was model and simulated using MATLAB/Simulink to validate thestability of the proposed system. The overall system was validated in real time implementation using microcontroller and Ultrasonic Sensor. The detection and recognition of objects, as well as making anautonomous decision to change its trajectory which is based on predetermined threshold distance of 5cmwere analyzed.
