Commande De Vitesse Par Mode Glissant D’une Machine Synchrone À Aimants Permanents

Résumé: In nowadays, permanent magnet synchronous motors (PMSM) are recommended in several industrial fields such as transportation and Aeronautics. This is because they are simple, reliable and less bulky than DC motors. Thus, their construction is simpler since they do not have mechanical interfaces between the mobile part and the static one. As a result, it increases their lifespan and avoids permanent maintenance. In the context of improving the performance of the control of the permanent magnet synchronous machine "MSAP", we present the technique of vector control regulated by sliding mode. In the first part, we presented a study of modeling and simulation of the synchronous machine with permanent magnets "MSAP", supplied by a three-phase network. In a second part, we presented a study of modeling and control of the synchronous machine with permanent magnets "MSAP", supplied by a voltage inverter and controlled by the sine-delta PWM technique. In the third part the PI vector control was introduced and used in order to have a decoupled model "decoupling between the torque and the flux" and to switch to a simplified control or we approach a linear model. And this control technique makes it possible to assimilate the "MSAP" to the DC machine with separate excitation from the torque point of view. A conventional PI controller is used for speed control. However, it gives acceptable results but not as performance. A general study on the sliding mode presented below was applied for the speed control of the PMSM. In the last part we are interested in this case by CV, This new adaptive control technique has made it possible to meet the expected objectives, in particular, the rejection of disturbances and to obtain the best results.
