PROJECT TITLE :

Receding Horizon Adaptive Second-Order Sliding Mode Control for Doubly-Fed Induction Generator Based Wind Turbine - 2017

ABSTRACT:

In this paper, a unique adaptive second-order sliding mode technique to optimize the efficiency of certain sorts of variable-speed wind turbines is developed and analyzed. A revisited type of a recent adaptation algorithm is proposed to accommodate the characteristics and control requirements of wind energy conversion systems (WECS), significantly model uncertainties and fast disturbances due to gusty wind effects. The revisited algorithm relies on appropriate receding horizon adaptation time windows rather than on mounted, adjacent, and nonoverlapping ones. This modification, which enhances the reactivity of the adaptation strategy against quick varying uncertainties, represents the main theoretical novelty of this paper. The proposed approach is successfully used to control a doubly fed induction-generator-based mostly wind turbine topology proving its suitability for this application area. The novel adaptive controller is extensively assessed through pc simulations over a full-order realistic model of the WECS under study.
