Contribution à la commande d’un moteur asynchrone destiné à la traction électrique

Abstract : The work presented in this thesis aims to contribute to the control and observation of the induction machines for electric traction. Several algorithms have been developed and implemented. After a fast presentation of the classical vector control, new approaches of non-linear control are proposed : the classical backstepping and integral backstepping. A second part deals with the observation and the estimation of parameters and states of the machine, based on MRAS-Sliding Mode structures on one hand and on synchronous filtering structures on the other hand. A detailed analysis of the operation at low speed led us to propose an original solution for a Sensorless control. The torque degradation in field weakening zone was treated by a voltage regulation controller. Finally, we proposed losses minimization algorithm for the Inverter-Machine set
