Modelling and Simulation of a BLDC Motor Speed Control System for Electric Vehicles

This paper describes the modelling and implementation of a sensorless control system (back-electromotive force (EMF) control) on a brushless direct current (BLDC) motor used in a traction drive system for an electric vehicle. The dynamic behaviour of the motor is first modelled, so speed proportional-integral (PI) controller, DC-alternating current (AC) inverter and commutation logic blocks are developed, in order to obtain a full control of the entire drive system, then, simulated using Simulink®. The elaborated study is based on determination of back-EMF, output current, motor speed and electromagnetic torque characteristics. Simulations results are presented to show the high performance and the efficiency of the simulated controlled system.
