H/sub ∞/ control for a variable-speed adjustable-pitch wind energy conversion system

Abstract

This paper presents a robust control design for a variable-speed adjustable-pitch wind energy conversion system with a uncertain multivariable controller is designed to turbine speed to extract maximum power from the wind and to allow pitch adjustment to power regulation and to use low speed wind. A change in the operating point of the plant was simulated for a nominal model and for a disturbed one showing the robustness of the controlled system.
