An H ∞ LPV control for a class of LPV systems using a descriptor approach: Application to a wind turbine mode

摘要

This paper is devoted to the synthesis of an H∞LPV state feedback controller, applied to a wind turbine which is described by an LPV model. Firstly, we focus on the modeling of wind turbines, to propose a model that describes as good as possible the system behaviour. A new approach that allows us, via LMIs, to design an LPV controller for a class of LPV systems is then presented. The interest of the approach is to decouple the system dynamic matrix and the lyapunov one using a desriptor approach. Finally, to illustrate the proposed control strategy, some simulation results are presented.
