Design of a large scale wind turbine generator set yaw system

PID-fuzzy adaptive yaw control algorithm is used and complete wind wheel position adjustment in order to automatically track the changes of wind direction. Input to the change of wind direction and wind direction, the output is kp, ki and kd, its fuzzy adaptive controller are designed. The simulation software used in this paper is Matlab-Simulink 7.0. Wind turbine to follow changes in wind direction changes, improve wind energy efficiency, implementing agencies to avoid the frequent movement, optimize unit performance, verify the effectiveness of the yaw control algorithm.
