The performance and effectiveness of a wind turbine depend on wind control and energy utilization. The control objectives in wind turbines are contingent upon the operational region of the wind turbine. These operational regions are divided into four areas based on wind speed and turbine performance. In the third region, also known as the full load region, the primary control objective is to limit the generated power to the nominal value and reduce mechanical loads on the blades. This is achieved by precisely adjusting the pitch angle of each blade individually to minimize the bending loads imposed on them. In this study, an adaptive individual pitch controller based on the Lyapunov function has been designed. To eva‎luate the controller's performance, extensive simulations were conducted on an accurate model of a 5 MW wind turbine using specialized software OpenFAST and Simulink. OpenFAST serves as a comprehensive simulator for the dynamic modeling of wind turbines, while Simulink is utilized for implementing and simulating the controller. The combination of these two software tools allows for a precise assessment of the controller's performance under various operational conditions. Simulation results indicate that the proposed controller effectively reduces bending loads and system oscillations. Furthermore, by accurately considering the system's nonlinearities in modeling, the controller's performance has significantly improved. This controller, with its ability to adapt to varying environmental conditions, represents a significant step towards enhancing the utilization of wind energy as a clean and renewable resource.
