Simulation of Four Four Quadrant Operation of Three Phase BLDC Motor Using Fuzzy

Ms. K. Suganya, Mr. S. Rameshkumar

Brushless DC (BLDC) motor drives are becoming more popular in industrial and traction applications. The control of BLDC motor in four quadrants is very vital. This paper deals with the fuzzy logic control of three phase BLDC motor. Without any loss of power the motor can be controlled in all the four quadrants. During regenerative braking period energy is conserved. The calculation capability of digital signal processor and controlling capability of fuzzy logic controller is used to achieve a precise control.
