Abstract

This work is dedicated to the vector control of the asynchronous machine; with orientation of the rotor flow. This technique makes it possible to decouple the control of the flow from that of the torque, similar to that of the dc machine with separate excitation. Indeed, the direct flow orientation method has been developed for a conventional speed control. Through the simulation results obtained, we noted a good behavior of this one for the various tests carried out, however shortcomings were observed concerning the sensitivity to disturbances of the load torque and their rejection time. But what strongly penalizes it is essentially its low robustness vis-à-vis the variations of the moment of inertia and especially compared to those of the rotor inductance. In fact the speed response is slightly affected, and for the changes of the rotor inductance, the decoupling of the machine deteriorates.
