Abstract
Rotating electrical machines play an important role in the
industrial world. Among
them, the three-phase squirrel cage asynchronous machines are
frequently used because of their robustness, their relatively simple
construction and their low cost. Nevertheless, during their lifespan, these
machines are submitted to external and internal stresses which can lead to
several failures.
We propose the modelling of the diagram multi windings of the
asynchronous machine allowing apprehending his behavior in presence or absence
of failures.
In the stage of estimate of the parameters, one proposes the
follow-up of the parameters sensitive to the defects, namely the rotor currents
and resistances of the rotor bars, by using the Extended Kalman filter.
We were interested in the indirect field oriented control order
of an asynchronous machine uti reading regulators PI and by fuzzy logic blur by
taking account of the presence of a rotor
defect. An analysis by simulation highlights the good
performances and the robustness of control command by fuzzy regulator
