The variable motor in a new type hydraulic wind turbine cannot maintain constant speed output, which is caused by random change of wind speed. A method based on singleneuron PID adaptive control was proposed for constant speed control of hydraulic type wind turbine. The AMESim software was used to build the hydraulic model of quantitative pump and variable motor, and the simulation was carried out by MATLAB/Simulink. The simulation results validate that the adaptive singleneuron PID control method can be used to enhance the hydraulic system’〖KG-*3〗s ability of antidisturbance and improve the accuracy of the variable motor constant speed control.
