The paper is devoted to the improvement of wind turbine control systems by developing fuzzy logic controllers with higher transient characteristics and lower computational identification costs compared to the PI controllers used. Based on the self-organization method, a fuzzy speed controller of the doubly-fed induction generator was synthesized, which is used in the vector control system of the transistor converter on the rotor side. The results of the simulation modeling of the proposed controller showed that it provides a lower transient time and a smaller error in the deviation of the rotation frequency from the reference signal. The implementation of the developed system on wind turbines contributes to increasing the efficiency of wind power equipment and the sustainability of alternative energy in general.
