SPEED OBSERVER IN THE VECTOR SYSTEM CONTROL OF THE DOUBLY FED MACHINE

The synthesis observer of the speed rotation of the rotor of a doubly fed machine with a vector control system was carried out. The synthesis of the observer is based on the second Lyapunov method, which allows determining the structure of the adaptation function, which adjusts the model of electromagnetic processes in such a way that the difference between the measured variables and their estimates goes to zero. The adaptation function, which uses the stator flux linkage and rotor current vectors, ensures the asymptotic stability of the speed observer.
