LPV robust gain-scheduling control for doubly fed induction generator wind energy conversion system

To deal with the uncertainty of the time varying and immeasurable system of the doubly fed induction generator WECS, a robust gain-scheduling controller based on LPV system is designed. In this controller, a partial linearized mathematical model is adopted and H∞ theory is used for harvesting the maximum power below the rated wind velocity. Simulation results show that the proposed LPV robust controller has good robustness, immunity and a better dynamic behavior.
