Sensorless Brushless DC Motor Control Using Type-2 Fuzzy Logic

Sensorless Control of a Brushless DC Motor

This paper uses a new position sensor less drive for brushless DC (BLDC) motors. In conventional sensor less control methods such as the back-EMF detection method, the performance is high only at a high speed range due to the fact that the magnitude of the back-EMF is dependent on the rotor speed. A solution is derived that estimates the rotor position by using an unknown input observer over a ...

Reduction of Commutation Torque Ripple in Sensorless Brushless DC Motor using Fuzzy Logic Controller

Brushless Direct Current (BLDC) motors are widely used due to high reliability, simple frame, straight forward control, and low friction. BLDC motor has the advantage of high speed adjusting performance and high power density. Speaking of the motor drive control, the most important part is commutation control. On the other hand, they show a high torque ripple characteristics caused by nonideal ...

Sensorless Speed Control of Brushless DC Motor with Fuzzy Based Estimation

This paper describes a simple way to control the Brush Less DC Motor (BLDCM) for electrical applications. To control this machine it is generally required to measure the speed and position of rotor by using the sensor because the inverter phases, acting at any time, must be commutated depending on the rotor position. The position sensors make the motor system more complicated and mechanically u...
