Wind power generation vane-change fuzzy control method

The invention relates to a wind power generation vane-change fuzzy control method, which solves the problems of low control quality and low steady-state performance of a wind power generation unit system and belongs to the technical field of application of wind power generation. The technical scheme comprises the following steps of: adjusting the magnitude of a modifying factor according to a membership function of a fuzzy object to achieve an adjustment control rule; introducing a fragmentation biquadratic Lagrange interpolation algorithm of a binary function into a self-setting fuzzy controller to convert discrete control variables into continuous control variables, so that the output power of a wind power generation unit can be relatively accurately and quickly controlled; therefore, the adjusting dead zone and the offset of the controller are eliminated, and the control quality of the system is ensured. In the wind power generation unit, due to the application of a control algorithm in which the self-setting fuzzy controller is combined with the Lagrange interpolation algorithm, wind power can be more accurately controlled, so that the wind power generation unit can better meet the requirements of power grids; and intelligent control over the wind power generation unit has become one of mainstream development directions of the current wind power generation technologies.
