Direct adaptive control for individual blade pitch control of wind turbines for load reduction

Journal of Intelligent Material Systems and Structures, 2015
In this article, a theory of adaptive disturbance rejection control is used to design an individual blade pitch controller to reduce the loading in a utility-scale wind turbine. The goal of the adaptive disturbance rejection control is to regulate the blade pitch angle individually to reduce the asymmetrical loading in blade due to vertical wind shear

Reduction of tidal turbines hydrodynamic loads employing bend-twist adaptive blades

3rd International Symposium on Environmental Friendly Energies and Applications (EFEA), 2014
The present paper is one of the first to investigate the use of bend-twist adaptive blades on a variable-speed pitch-controlled tidal turbine in order to reduce hydrodynamic loads. The realisation of the substantial unexploited hydrokinetic energy of tides is currently driving hydrokinetic turbine research.

Background of Wind Turbine Blade-Pitch Load Reduction Control

, 2018
The aim of this chapter is to provide some background regarding to the wind turbine operations, modelling and control. Firstly, this chapter introduces the basic operation of a typical modern wind turbine in Sects. 2.2 and 2.3 and followed by the modelling aspect of a wind turbine including aerodynamics, rotor, blades and tower in Sect. 2.4.
