Identifier of Stator Flux Linkage in the Vector Control System of Doubly Fed Machine
Currently new structures of sensorless control systems for AC electric drives are being actively developed. Reducing the number of sensors reduces the cost of the control system, simplifies its operation and increases the reliability of the electric drive. To build a vector control system, you first need to find a way to determine the spatial position of the reference vector. In field-oriented control systems the flux vectors of the stator, rotor or air gap are taken as reference.
