Commande multivariable du moteur asynchrone triphasé à cage par variation de fréquence

Abstract

Three phase squirrel cage asynchronous motor control fed by rectifier and voltage inverter is treated as a MIMO system. Motor behaviour has been simulated using different values of stator supply frequency, to justify the choice of voltage inverter. Established simulation program allows to know all characteristics by inserting the parameters of the motor. The obtain result is used for the analysis and the synthesis of the system by MATLAB software.
