Sensorless Vector Control of Bldc Using Extended Kalman Filter

This Paper mainly deals with the implementation of vector control technique using the brushless DC motor (BLDC). Generally tachogenerators, resolvers or incremental encoders are used to detect the speed. These sensors require careful mounting and alignment, and special attention is required with electrical noises. A speed sensor need additional space for mounting and maintenance and hence incre...

AVR498: Sensorless control of BLDC Motors using ATtiny261/461/861

Simplified Sensorless Control for BLDC Motor, Using DSP Technology

This paper describes a simple way to control, in a sensorless way, a Brushless DC (BLDC) motor for electric vehicle applications. To control this machine it is generally required to count with a position sensor because the inverter phases, acting at any time, must be commuted depending on the rotor position. Encoders and resolvers have been used for sensing rotor position with respect to stator...

Optimal Sensorless Four Switch Direct Power Control of BLDC Motor

Brushless DC (BLDC) motors are used in a wide range of applications due to their high efficiency and high power density. In this paper, sensorless four-switch direct power control (DPC) method with the sector to sector commutations ripple minimization for BLDC motor control is proposed. The main features of the proposed DPC method are: (1) fast dynamic response (2) easy implementation (3) use o...

Reduction in Commutation Torque Ripple in Sensorless Bldc 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 power density. Speaking of the motor drive, the most important part is commutation control. On the other hand, they show a high torque ripple characteristics caused by no ideal commutation c...
