Détection de la corrosion à l’aide d’une nouvelle méthode basée sur des capteurs et antennes inspirée de la technologie RFID

Abstract

Controlling of asynchronous machine can be done using several techniques, each of which offers well-defined dynamic and static performance. In this work, we propose the control of the asynchronous machine by input-output linearization. The asynchronous machine has advantages that we cite: robustness, reliability, less frequent maintenance and low cost, it is more used in the applications requiring the variation of the speed. But with all this they have a nonlinear and multi-variable system strongly coupled with fast dynamics and parameters varying in time. However, its non-linear nature makes it difficult to control; our goal is the implementation of control by linearization input-output with the objective to improve the trajectory and guarantee stability and robustness, which consists in eliminating non-linearity in the machine and solving the coupling problem between the flow and the speed rotation. The control law is developed theoretically, the results of the study are expressed in starting mode and in load mode that allows the system follows their reference model. The results obtained show the performance and robustness of the input-output linearization control.
