The work presented in this paper has two major aspects: (i) investigation of a simple,\nyet efficient model of the NREL (National Renewable Energy Laboratory) 5-MW reference wind\nturbine; (ii) nonlinear control system development through a real-time nonlinear receding horizon\ncontrol methodology with application to wind turbine control dynamics. In this paper, the results\nof our simple wind turbine model and a real-time nonlinear control system implementation are\nshown in comparison with conventional control methods. For this purpose, the wind turbine control\nproblem is converted into an optimization problem and is directly solved by the nonlinear backwards\nsweep Riccati method to generate the control protocol, which results in a non-iterative algorithm.\nOne main contribution of this paper is that we provide evidence through simulations, that such an\nadvanced control strategy can be used for real-time control of wind turbine dynamics. Examples are\nprovided to validate and demonstrate the effectiveness of the presented scheme.
