A feedback linearization control strategy for maximum power point tracking of a PMSG based wind turbine

This paper presents a feedback linearization control (FLC) scheme for maximum power point tracking (MPPT) of permanent magnet synchronous generator (PMSG) based wind turbine (WT). The FLC strategy can fully decouple and linearize the original nonlinear system and thus provide a optimal controller crossing a wide range operating conditions. It performs better than the conventional vector control (VC) with proportional-integral (PI) loops designed based one operation point as operation points varies. The Verified and performance of the proposed control strategy are confirmed by simulation studies in comparison with the VC.
