Abstract
Aiming at the problem of system vibration during yawing of large wind turbines, the mathematical model is obtained by simulating the structure model of the yawing system, which is then represented by a general free vibration equation. The system vibration equation is modeled and simulated by MATLAB/Simulink. The model is controlled by PID, Fuzzy PID and Optimal Fuzzy PID intelligent algorithm, and the control result is obtained. By comparing the control results between different algorithms, it can be shown that although the PID algorithm and the Fuzzy PID algorithm can obviously and effectively control the vibration model of the yaw system, and the control effect of the Fuzzy PID algorithm is better than that of the PID algorithm, the PID parameters obtained by the “trial and compact method” are not the optimal parameters, which will affect the control effect of the Fuzzy PID. The Optimal Fuzzy PID algorithm can automatically optimize by MATLAB program to obtain the optimal PID parameters and achieve the optimal control effect.
