Field Oriented Control Electrical4U

Vector control, also called field-oriented control (FOC), is a variable-frequency drive (VFD) control method in which the stator currents of a three-phase AC or brushless DC electric motor are identified as two orthogonal components that can be visualized with a vector. One component defines the … See more Technische Universität Darmstadt's K. Hasse and Siemens' F. Blaschke pioneered vector control of AC motors starting in 1968 and in the early 1970s.

From simulation result, when the torque is higher, then response of the motor is faster to achieve nominal rotational speed. Otherwise, lower torque that applied to the load cause longer transient session.

BRIDGING … Web2.1 Direct FOC (DFOC) Flux vector, in this method is to be measured by mounting a sensor in the air-gap, which senses the flux. Because of a sensor, the construction of motor becomes complex. So it is not widely used. 2.2 Indirect FOC (IFOC) In this method the flux vector of the rotor is estimated by using the FOC equations.

WebThe aim of the FOC method is to control the magnetic field and torque by controlling the d and q components of the stator currents or relatively fluxes. With the information of the stator currents and the rotor angle a FOC technique can control the motor torque and the flux in a very effective way. WebApr 2, 2024 · The second family of sensorless motor control methods relies on a back-EMF Sliding-Mode Observer (SMO). These techniques stem from the following observation: in a synchronous machine, the frequency of the back-EMF (counter electromotive force) is directly linked to the rotor mechanical speed. Therefore, if one can determine the …
