This paper is focused on design of a wind turbine optimal yaw control system based on very short- term wind predictions. The optimal controller performance is evaluated with respect to the power production maximisation and structural loads minimisation goals that are joined together in a single performance function expressing the profit of the wind turbine control system operation. Designed optimal yaw controller performance is compared to the baseline controller in the professional aeroelastic simulator GH Bladed. The results show effectiveness of the developed optimal wind turbine yaw angle controller, since it demonstrated damage equivalent loads reduction and power production increase.
