Abstract
A nonsingular fast terminal sliding mode control of wind turbine based on combined power and load feedback is proposed to deal with the problem of power instability and load imbalance of wind turbine when the wind turbine operates above the rated wind speed. The control strategy uses three independent nonsingular fast terminal sliding mode controllers to reduce the Tilt moment, Yaw moment and stable power on the hub fixed coordinate system respectively. Finally, the 2MW wind turbine is simulated by MATLAB and Bladed software, and the control strategies of three PI controllers are compared. The results show that the control strategy not only has a good effect on stabilizing the output power, but also has a prominent performance in reducing the unbalanced load of the wind turbine.
