The training techniques, allows a wide range of use of the asynchronous machine with good

performance, tell her great robustness, reliability and electromagnetic low cost. The vector control

strategy takes into account the dynamic structure of the machine to have training systems robust high

performance. In the sensorless speed control of induction motors for the information of the rotor speed

and extracted the electrical terminals of the stator (voltage, current) .

Vector control of induction motors allows to reduce the control of an induction motor similar to that of

a machine with separate excitation current contained linear control, this control requires an estimate of

the amplitude and direction of flow in the rotor.

The estimated speed of the engine, which uses the MRAS technique based on reactive power, has been

proposed and used in this work to achieve this goal. -The　training　techniques,　allows　a　wide　range　of　use　of　the　asynchronous　machine　with　good
