Abstract:According to the vibration control problems of the offshore wind turbines under seismic load and wind load,the mechanical model of magneto-rheological (MR)damper and the relationship between the damping force and parameters of MR damper are presented here.The action principle of the fuzzy control algorithm in semi-active control is studied,and the Simulink simulation model is established,then the vibration control of the offshore wind turbines under the effects of seismic load and wind load is analyzed.For reducing the acceleration and displacement of the offshore wind turbines un-der the wind load and seismic load,the MR damper is used in the wind turbines.The result illustrates that this control method could effectively reduce the acceleration and displacement under the wind load and seismic load.
