Commande par linéarisation entrée-sorties du couple et du la machine asynchrone

Abstract

The objective of this work is the application of the techniques of feedback linearization inputoutput based on the theory of the differential geometry (CNL), to the induction motor where it represented by non linear model. The strategy of input-output feedback linearization permits to decouple and linearized the model of the induction motor. The behavior of this last is chosen according to the method of the imposition of the poles. The algorithm of order by linearization input-output so definite is put in value by test simulation on the motor of induction. His performances are compared to those of the classic field oriented control. Besides, the survey of the realization of the non-linear order in the case of the non availability of the states is also solved by the conception of an observer of states. Finally, the performances of the whole non-linear controller observer inverter are presented and are discussed.
