Abstract
Because of high wind energy potential and many other advantages, offshore wind energy is drawing considerable research interest. The researches have shown that more energy can be captured if wind turbines are installed farther from the shore. For this reason, research has been done in floating type of platform and showing promising results. But, floating platform exhibits additional motions due to wind and incident waves which ultimately degrade the amount of power that can be captured, demanding more advance type of control design. Also, dynamics of wind turbine is highly complex and poorly known, which adds extra complexity in controller design. In this paper, we introduce an Adaptive Pitch Controller to regulate the rotor speed and power, and implement to NREL’s 5 MW offshore wind turbine with floating platform. We compare the simulation results with the baseline gain scheduled PID controller. The preliminary simulation results show that the performance of adaptive controller is comparable to that of baseline controller.
