Abstract

BLDC motor is a rotating synchronous machine. BLDC motors are electronically commutated. This paper discusses digital pulse width modulation control implemented in FPGA for a BLDC drive in both motoring and generating modes of operation with Regenerative Braking System (RBS). Regenerative braking can improve energy usage efficiency and can prolong the driving distance of Electric Vehicles (EVs). The proposed system includes BLDC motor control utilizing the traditional PID control, and the distribution of braking force adopts fuzzy logic control. RBS has the ability to recover energy and ensure the safety of braking. The implementation of digital pulse width modulation control using FPGA results in a considerable reduction of size and the cost of the system.
