Due to the poor performance of current methods in maximum power tracking fuzzy control for variable-speed wind tur-bines,the generator set's output voltage exceeds the limit value,and the output power deviation is also relatively large,which cannot achieve the expected control effect.Therefore,a fuzzy control method for maximum power tracking of variable-speed wind turbines is proposed.This method describes the energy capture of wind turbines,determines the input and output variables for fuzzy control,identifies errors based on the relationship between wind turbine energy and generator output power,and uses fuzzy control theory to fuzzify and defuzzify the errors,obtain fuzzy control output vectors,and achieve maximum power tracking fuzzy control of variable speed wind turbine generators.Experimental results have shown that under the application of the design meth-od,the generator set's output voltage does not exceed 0.1 V,the power deviation does not exceed 0.1 W,and it can effectively track and control the maximum output power of the generator.
