In order to capture the maximum wind energy and improve the efficiency of wind turbine, the yaw control system was researched. This system takes the initiative to windward. The relative wind direction is measured by the wind sensor. According to the relative wind direction, yaw angle is calculated by the DSP and generate the drive pulse. Then the stepping motor is controlled to turn or turn over by the subdivision con-trol technology to make the turbine windward. Through this way, the yaw control system can track the wind direction automatically. Experimental results show that using DSP control, the real-time performance of yaw system is good and operation precision of stepping motor is high by the subdivision control technology. There-fore, the yaw system tracks the wind direction quickly and exactly.
