ABSTRACT
The control of an AC machine is generally carried out by two technique a classical techniques such as (scalar control, vector control, and direct torque control) and modern control techniques such as nonlinear controllers. For a situation equivalent to that of the current machine, we introduce the technique of vector control. The principle of it is to replace the model of the asynchronous motor with a structure similar to the direct current motor. The field-oriented control is based on the choice of the frame of reference in which the axes are oriented, which are the stator or rotor flux orientations respectively. Oriented vector control of rotor flux is frequently used because it eliminates the influence of the leakage reactance rotor and stator and gives better results than methods based on the orientation of the stator flux or airgap. However, controlling the doubly fed induction motor from the rotor side yields to undesirable output oscillations for the mechanical speed.
