High performance BLDC motor control for electric vehicle

Abstract

This paper presents about design of high performance brushless dc motor (BLDC) control for electric vehicle (EV) which focusing on rear differential of electric car uses electronic control system or well known as electronic differential system (EDs). The advantage of EDs is help to adjust wheel speed while cornering by driving two BLDC motor attached to two rear wheels that two wheel speed is different. This system can accurately control process by monitoring output and feeding some of it back to compare actual output with desired output so as to reduce the error. It is well known as closed loop control system. The speed of BLDC is experimentally measured by a tachometer. The steering angle and speed of EV is calculated by equations derived from Ackemuuui-Jesntsnd model using Arduino. Load simulation using MATLAB Simulink. The experimental results electronic differential using will enhances efficiency of electric vehicle driving system.
