Obed Department of Electrical Engineering Department of Electrical Engineering University of Basrah University of Basrah ABSTRACT [3-5]. Basically, two methods, sensor and sensorless, are used Increasing the methods of order calculus for Fractional Order to detect the rotor position. The BLDC motor is multi- Proportional Integral Derivative (FOPID) controller leads variable and non linear system [6-8 ], so it is difficult to to a wide applications for this type of controller in control get accurate and reliability control performance result for systems. A closed loop speed control for BrushLess Direct BLDC motor using conventional control linear method. Current (BLDC) motor with FOPID controller runs the . motor very close to the reference speed, provides a good In this paper a fractional order PID controller is used to performance and robustness compared with a corresponding get more accurate and high reliability than conventional system using conventional PID controller. In this paper, the method. The proposed controller is used to contr
