Abstract Torque vibration is an important reason of wind turbine drive train fatigue damage. The nonlinear and uncertainty characteristics in drive train are analyzed firstly in this paper. A torque vibration control method is designed based on active disturbances rejection control technique. The external disturbances and uncertainties of drive train, which include gear engaging dynamic stiffness, gear engaging error and flexible coupling nonlinear stiffness and damping etc., are integrated as compositive disturbances. The compositive disturbances are estimated with extended state observer and compensated during torque vibration control. The torque vibration controller is evaluated based on a 3MW doubly fed variable speed wind turbine. The simulation result shows that the gearbox torque vibration is mitigated obviously on the premise of not affecting generator output power.

Key words： Wind turbine torque vibration control active disturbance rejection control extended state observer
