    Abstract:

    In order to solve the problem that the traditional PID could not achieve good control effects in the wind turbine with large inertia and strong coupling, a wind speed feed-forward and variable region fuzzy pitch controller was proposed. According to the power error and its rate of change, the contraction-expansion factor was obtained by fuzzy inference. And this method avoid the difficulty of determining the contraction-expansion factor model and its parameters. The dynamic compensation of pitch angle was realized by using the method of wind speed feed-forward, and the response speed of the system had also been improved. The simulation results showed that when the wind speed exceeds the rated wind speed, this method could made the speed and the output power more stable.
