Nonlinear Control of a Doubly Fed Induction Generator Supplied by a Matrix Converter for Wind Energy Conversion Systems

Abstract

This paper deals with a variable speed device to produce electrical energy on a power network, based on a doubly-fed induction generator fed by a matrix converter. In the first place, we carried out a study of modelling on the matrix converter controlled by the venturini modulation technique. In second place, we developed a model of the doubly fed induction generator. In order to control the
power flowing between the stator of the DFIG and the power network, a control law is synthesized using two types of controllers: fuzzy logic and sliding mode. Their respective performances are compared in terms of power
reference tracking, response to sudden speed variations, sensitivity to perturbations and robustness against machine parameters variations.
