State-of-the-art in wind turbine control: Trends and challenges
Jackson G. Njiri,Dirk Söffker +1 more
TL;DR: In this paper, a review of various control strategies that are used in wind turbine systems, both in low and high wind speed regions focusing primarily on multi-objective control schemes is presented.
Journal ArticleDOI
Wind turbine aerodynamics and loads control in wind shear flow
TL;DR: In this paper, a lifting surface method with time marching free wake model is used to investigate the periodic unsteady nature in the wind shear, and the blade airloads and performance of the turbine are also predicted under IPC control.
Journal ArticleDOI
Overview of Modelling and Advanced Control Strategies for Wind Turbine Systems
TL;DR: In this paper, the authors provide an overview of the challenges of modelling and control for very demanding systems, such as wind turbine systems, which require reliability, availability, maintainability, and safety over power conversion efficiency.

Two LQRI based Blade Pitch Controls for Wind Turbines
Sungsu Park,Yoonsu Nam +1 more
TL;DR: In this article, a separate set of collective and individual pitch control algorithms were proposed to control rotor speed and blade bending moments at the same time to improve the trade-off between rotor speed regulation and load reduction.

Multi-resolution wavelet pitch controller for spar-type floating offshore wind turbines including wave-current interactions
TL;DR: A wavelet multi-resolution based individual pitch control strategy for spar-type floating offshore wind turbines (FOWTs) is proposed and its performance under joint wind-wave-current loads considering the effects of wave-current interactions is investigated.

Aerodynamics of Wind Turbines
TL;DR: In this article, the authors present a detailed review of the aerodynamics of wind turbines with respect to structural dynamics and control, including a new control chapter that includes details on how to design a classical pitch and torque regulator to control rotational speed and power.
Journal ArticleDOI
Individual Blade Pitch Control for Load Reduction
TL;DR: The possibility of using pitch-regulated wind turbines as a way of reducing loads has been suggested many times over the years, but the idea has yet to gain full commercial acceptance as discussed by the authors.

Control of variable-speed wind turbines: standard and adaptive techniques for maximizing energy capture
TL;DR: The question of theoretical stability of the torque controller is addressed, showing that the rotor speed is asymptotically stable under the torque control law in the constant wind speed input case and L/sub 2/ stable with respect to time-varying wind input.
Standard and adaptive techniques for maximizing energy capture
TL;DR: In this article, the authors used the Controls Advanced Research Turbine (CART) as a model for this article's research, which is located in Golden, Colorado, at the U.S. National Renewable Energy Laboratory's National Wind Technology Center.
