Fractional-order fuzzy controller for a PMSG wind turbine system

Abstract

This paper presents a novel Takagi–Sugeno (T-S) fractional-order fuzzy logic control for a permanent magnet synchronous generator wind turbine (PMSG-WT) system. The proposed control strategy is composed of two parts. Firstly, a fractional reference model of the PMSG-WT nonlinear system is provided using T-S model and fractional calculus in order to ensure an accurate and robust model of the system. Secondly, the feedback controller gains are determined by resolving a set of linear matrix inequalities. The effectiveness and the validity of the proposed approach are demonstrated using numerical simulations.
