Robust Control of a Doubly Fed Induction Generator (DFIG) Fed by a Direct AC-AC Converter

The aim of this paper is to propose a robust control method for a doubly-fed induction generator fed by a direct AC-AC converter used in wind energy conversion systems. First, we carried out a study of modelling on the matrix converter controlled by the venturini modulation technique. Thereafter, stator active and reactive powers are regulated by controlling the machine inverter with two different controllers : proportional-integral and Sliding mode. Simulations results are presented and discussed for the whole system. Streszczenie.
