Abstract :
As wind turbine rated power increase, the potential danger of the vibration is serious result of the rotor diameter and the hub height is longer and higher. Wind turbine vibrations will cause futile mechanical loads, such vibration loads maybe result to serious damage of wind turbine. In order to achieve vibration suppression, taking the uncertainty of turbulence which the operate environment of wind turbine into consider, H control methods is utilized in wind turbine to decrease vibration. The state space of wind turbine in cycle life is established to analyse the character by GH-bladed. Effectiveness of controller based on the H control in vibration control field is verified by Matlab. Simulation results and validation results show that the purposed control strategy is effective in terms of wind turbine tower vibration.
