Fuzzy and PI Based Speed Control of BLDC Motor using Bidirectional Converter for Electric Vehicle Application

Abstract

Fuzzy logic control can be used in BLDC motor to control the four quadrants of operation so as to avoid power loss. In this study, a fuzzy based controller for speed control of BLDC motor is done, and it is compared with the conventional PI controller-based speed control technique. In addition to this, a bi-directional converter is used to achieve battery charging during regeneration and to charge the battery externally as well in two different modes of operation by controlling the converter switches gating pulses. A boost converter is also suggested to improve the power quality during charging mode from the external AC source. This is well suited for electric vehicle applications.

Keywords: Brushless DC motor, regeneration, bi-directional converter, fuzzy logic controller (FLC), CC-CV charging
