In this paper, the authors present an intelligent speed control system based on self tuning fuzzy PID controller for a brushless DC motor. PWM based motor current control is implemented with the help of three hall sensors placed around the motor shaft and a three phase inverter model is implemented for motor commutation. Dynamic performance of electromagnetic torque developed is analyzed for this model. Traditional speed control system of BLDCM introduces conventional PI regulator in outer speed loop which debases the performance of whole system.
