Double Flux Oriented Control for the Doubly Fed Induction Motor

摘要

In this article, a new vector control intended for an induction motor in double fed mode is proposed. It is based on the principle of a double flux orientation of stator and rotor at the same time. Therefore, the orthogonality created between the two oriented fluxes, which must be strictly observed, leads to generate a linear and decoupled control with an optimal torque. The obtained simulation results show the feasibility and the effectiveness of the suggested method, which, in fact, allows to avoid the open loop stability problems inherent to this mode of power supplying of wound rotor induction machine.
