Speed Control ofln-Wbeel Brusbless Motor For Hybrid Electric VehiCle

This report, Speed Control of In-Wheel Brushless Motor for Hybrid
Electric Vehicle, presents the development of a study which implements closedloop
speed control of a 3-phase, brushless, permanent-magnet in-wheel motor for
a hybrid electric vehicle using external controller and motor drive. An in-wheel
motor can convert an ordinary car into a split-parallel type hybrid electric vehicle
by replacing the rear wheels with in-wheel motors. The purpose of conducting this
project is to investigate the a method to control the speed of the motor with
conventional PID , using ari off-the-shelf motor drive from Kelly Controller and
NI Compact Rio as the controller. Furthermore, this project also present a study
and analysis on the characteristics of the Brushless Direct Current (BLDC) motor
and a study about the behavior of an additional control strategy which is speed
control. Data and results will be obtained from field experiments ori the actual
motor in the lab. A Brushless Direct Current motor uses electronic commutation
for basic operation. So, the basic brushless motor drive system will perform the
commutation to start the brushless motor and the wheels of the car will also rotate.
The control system will be implemented using NI LAb VIEW Real-Titne software.
