Interval Type-2 Fuzzy Maximum Power Point Tracking Control for Wind Power Buck Coversion Systems
نویسندگان
چکیده
This paper develops a PI-like interval type-2 (IT2) fuzzy maximum power point tracking (MPPT) control method for a class of wind power generation and battery charging systems with DC/DC buck converters. After the brief model descriptions of the wind power turbine, generator and DC/DC buck converter, the proposed MPPT controller is designed using IT2 fuzzy control logics and its asymptotical stability is discussed. The effectiveness and merit of the proposed MPPT controller are exemplified by conducting several simulations via Matlab/Simulink and three experiments. The proposed controller is shown superior by comparing to a conventional PI MPPT controller and a PI-like type-1 fuzzy MPPT controller.
