literature.rockwellautomation.comSensorless Vector Control, Flux Vector Control, and Field Oriented Control. • Volts/Hertz control is a basic control method, providing a variable frequency drive for applications like fan and pump. It provides fair speed and starting torque, at a reasonable cost. • Sensorless Vector control provides better speed regulation

www.ia.omron.comVector Control with Encoder Feedback As opposed to sensorless vector control, control is performed using feedback from an encoder. The encoder is also called a pu lse generator, and this type of control is also called vector control with PG. With this method, the inverter monitors the output voltage, the

Sensored (Encoder-Based) Field Oriented Control of Three ...
ww1.microchip.comFOC can be implemented using a speed sensor or speed sensorless approach. For high precision control applications, sensored control is preferred. In sensored FOC implementation, rotor position and mechanical speed are determined using an encoder or resolver. This Application Note describes the encoder-based implementation in this document.

Sensorless Field Oriented Control (FOC) for Permanent ...
www.microchip.comIn Field oriented control, stator field is continuously updated based on the position of the rotor field. By continuously pulling the rotor to a new position, the rotor is always magnetized with a new vector, thus reducing torque ripple. Applications where low speeds are required take advantage of this property of FOC.
