Fuzzy based reconfigurable controller for BLDC motor

摘要

The development of advanced motor drive increases rapidly, because of its higher performance characteristics and reliability. The conventional motor drive technology is replaced with Brushless DC motor (BLDC) drive due to its higher efficiency, lower maintenance, high reliability and high torque to weight ratio. This paper focuses on reconfigurable controller using fuzzy logic technique for a BLDC motor for variable frequency and variable duty ratio operation. In digital controller of brushless DC motor, the control accuracy is of a high level, and it has a low response time; furthermore, this technique is implemented using reconfigurable Vertex II Pro development board. This proposed energy efficient controller consumes 70 mW, which is less compared to other conventional controllers.
