FUZZY BASED VECTOR CONTROL METHOD FOR BLDC MOTOR DRIVE WITH FIVE-SWITCH THREE-PHASE TOPOLOGY

Abstract

The Brushless DC Motor is a type of permanent magnetic motors which will be having high performance in recent years and replaced the Brushed DC Motors. The BLDC motors have higher efficiency and precise dynamic response increases in the Industrial applications. This paper proposed that the low cost design of the three phase Brushless DC Motor and it is analyzed with the vector control scheme. The working principle of the BLDC is with the help of five-switch control scheme can be implemented here. The proposed method is also reduces the current distortions where the frequency is varies with the speed and load. Later the current control is implemented with the Fuzzy logic control to maintain the accurate rating of the current. The fuzzy logic control scheme is implemented to reduce the current distortions and maintain the good speed. However the DC link of the five switching inverter is used here for the boosting of the voltage.  The effectiveness of the Fuzzy based vector controlled method with the five-switch model is designed and implemented in Simulink/Mat lab
