Sliding mode control of a permanent magnet synchronous machine FED an MLI tension inverter

Abstract

In this article, we study the control by sliding mode (CSM) applied to the permanent magnetsynchronous machine (PMSM) supplied with a tension inverter with triangulo-sinusoidal -MLI. Thecontrol by sliding mode is well adapted to the nonlinear systems. It is characterized by properties ofrobustness with respect to the external disturbances and parameters variations . The sliding surfaceis given on the basis of the system and desired performances. While the law of control is selected withan aim of ensuring the convergence conditions and sliding i.e. the attractivity of commutationsurfaces. A comparative analysis of all CSM advantages to those of the classical control (PI) wasdeveloped in last stage to highlight the performances of this technique. The various results obtainedin simulation allow an evaluation of the robustness and performances of this mode of control variablestructure.
