Résumé

The induction motor squirrel cage that is deemed by its strength, high torque mass, robustness ,and its relatively low cost ... etc, , meanwhile, it benefited from the support of industry since its invention ( invention by Tesla the late nine-teenth century).
Unfortunately, these advantages are accompanied by a high complexity of the physical interactions between the stator and the rotor. Therefore, dynamic control requires complex control algorithms in contrast to its structural simplicity. In re-cent decades, many techniques of control of the induction machine, such as tech-nical oriented control or Field Oriented control, have emerged and are currently used to enjoy the benefits of the asynchronous machine for applications where va-riable speed is essential.
The high operating control of the induction machine began with the invention of the oriented vector control in the late 60s flux. Before that time control of the in-duction machine was limited to scalar commands.
This operating control does not provide a decoupling between the flux and torque. To illustrate this, the torque of a cage induction motor has to be increased by in-creasing the slip , the flux is affected by a decrease ; therefore the torque control is dependent of the stream, for this the inherent coupling between these two va-riables makes conventional techniques less efficient.
