Contribution to stator flux orientation vector control of an induction machine

The paper presents a control strategy for induction motor supplied by voltage inverter. The induction machine with control strategy should provide, at the constraining requests, response with high performances in electromagnetic torque and speed. Using the Matlab/Simulink software, we test Indirect and direct field oriented control (IFOC, and DFOC). Both of them achieve the goals for dynamic of torque and stator flux, but are both depending on the unpredictable machine parameters variation.
