Wind Power Variable-Pitch DC Servo System Based on Fuzzy Adaptive Control

The paper aims to expand a way of applying the fuzzy adaptive control strategy by analyzing the advantages and disadvantages of traditional PID control strategies. In view of the high requirements of the variable-pitch servo system for megawatt-level wind turbines, combined with the control characteristics of series-excited DC servo motors, a wind power variable-pitch DC servo system based on fuzzy adaptation was designed. The superiority and reliability of the fuzzy adaptive PI control method are verified by using simulation tools to carry out simulation experiments, and then the experiments are carried out by DC series servo motor and servo driver. In summary, the performance of the wind power variable pitch DC servo system is excellent.
