Rana, Kapil Deo, Scientists, Avionics Group, ARDE, Pune (DRDO), India [email protected] Abstract: In this paper, an efficient simulation model for Fuzzy logic controlled Brushless DC Motor drives using Matlab / Simulink is presented. Here Model of BLDC motor is based on State-space and its speed loop control is based on Fuzzy logic PID controller. A three phase inverter model is implemented for Motor commutation in six steps and PWM based motor Current Control with help of three Hall Sensors which are placed at 120 electrical degrees apart around the motor shaft. Dynamic performances (i.e. Torque and Speed) and currents and voltages of the inverter components are analyzed for this model. The modeling, simulation and two loop control of BLDC have been done in MATLAB\SIMULINK software.
