Description: 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.
