Structural vibrations caused by turbulent wind inflow and model uncertainties present significant challenges to the safety and efficient operation of wind turbines. This paper develops a damping enforcement control strategy that integrates an extended state observer with a disturbance compensation module featuring an adjustable gain, thereby enabling enhanced vibration attenuation without compromising power output. Simulation results under realistic wind conditions validate the effectiveness of the method in enhancing load alleviation, improving fatigue resistance, and maintaining dynamic stability.

摘要

Structural vibrations caused by turbulent wind inflow and model uncertainties present significant challenges to the safety and efficient operation of wind turbines. This paper develops a damping enforcement control strategy that integrates an extended state observer with a disturbance compensation module featuring an adjustable gain, thereby enabling enhanced vibration attenuation without compromising power output. Simulation results under realistic wind conditions validate the effectiveness of the method in enhancing load alleviation, improving fatigue resistance, and maintaining dynamic stability.
