The traditional reference bias control (RBC) algorithm has the problem that the rotor speed cannot be effectively controlled in the case of sudden increase of aerodynamic power, for which is caused by the delay of the reference signal. In this paper, the wind speed is obtained by LiDAR, and the accurate pitch angle command is obtained by using the inverse system method, which is used for the feedforward control of the reference bias signal. In the case of large changes in wind speed, the generator speed is well suppressed. Compared with the traditional RBC algorithm, this method accelerates the switching speed of torque control, and then improves the dynamic characteristics of the rotor speed in the transition region.
