| Abstract: | With consideration for the high standards for the stability of the yaw system as needed for the large scale of wind turbines these years, this paper applies the fuzzy control theory to the yaw system. Firstly, the working principle of the yaw system is analyzed. Secondly, a fuzzy controller is designed and the corresponding software flowcharts are compiled towards the control process. At last, the simulation model of the system is set up in the platform of Matlab/Simulink, and then a simulation experiment is conducted. The control effect between fuzzy control strategy and PID control method is compared and analyzed. The result shows that the fuzzy controller has better overall performance and it can satisfy the requirements of both control accuracy and stability. |
