Renewable energy is becoming more important all over the world, and wind energy is the most important role in renewable energy right now. Many countries are producing and building wind turbines, and the turbine size is becoming larger. The larger a turbine is, the more expensive it will be. However, wind turbines will fail when overspeeding. So we need control algorithms to protect the turbine and to develop power output efficiency. The study concerns the implementation of adaptive control on a Horizontal Axis Wind Turbine (HAWT). This paper focuses on the implementation of adaptive control in the Transition Region between Region 2 and Region 3. For Region 2, Adaptive Disturbance Tracking Control (DTC) with a certain tracking ratio will ensure the wind turbine has maximum power capture. Using the same Adaptive DTC in the Transition Region, but with a switching mechanism for different tracking ratios, the wind turbine will have smooth performance for connecting Region 2 and Region 3.
