Reglage de la vitesse d’une machine asynchrone par logique flou et conventionnel

الملخص EN

Performances assured by the conventional regulator of the variable speed drive may be insufficient in controlling systems subjected to variations parameters.

This paper, present a performances comparison between conventional control and fuzzv logic, applicated for induction machine We present at first the nmdelisation of the asynchronous machine and principle of the control by for its application to the command of the speed.

After the simulations of behaviours the state variables and the characteristic parameters variation of the machine.

Finally, a comparative study between the two techniques of the control allowing to evaluate theirs sensibilities to parametric variations
