摘要

The current study focuses on mitigating the effects of wind and wave disturbances on the power output, rotor speed, and platform dynamics of floating wind turbines, while tackling the strong coupling and dynamic interference present in offshore environments. This study utilizes an OpenFAST-Simulink co-simulation framework to analyze the dynamic characteristics of the NREL 5 MW semi-submersible wind turbine system. A fractional-order PIDD2 (FOPIDD2) controller is developed on top of the OpenFAST baseline framework for collective blade pitch regulation. The developed collective pitch controller can effectively suppress the external environmental disturbances, improving the robustness of the system against disturbances. Additionally, the parameters of the FOPIDD2 controller are fine-tuned using the Ant–Lion optimization method to improve system regulation. Finally, the proposed FOPIDD2 controller is systematically evaluated and compared with the FOPID, PIDD2, and OpenFAST baseline controllers under different wind and wave scenarios. Simulation results indicate that the FOPIDD2 controller enhances both the smoothness of power output and the accuracy of rotor speed regulation, thereby effectively suppressing the oscillatory movements (surge, pitch, and roll) of the platform, and improving the overall dynamic stability and robustness of the wind turbine system.
