Optimal active yaw control for a wind turbine

In this work a control strategy based on the mathematical model of an active yaw system for a 20 KW horizontal axis wind turbine is proposed. It allows to increase its efficiency in the presence of changes in the intensity and direction of the wind. The inverse optimal control strategy is implemented based on the mathematical model using the equations of state that represent the dynamics of the yaw system, whose model was obtained with the FAST program, specialized software for modeling wind turbines, which allows obtaining the mathematical model of the orientation system in a more precise way. The results are presented via simulation, where the control strategy is validated in the presence of disturbances. The contribution of this work lies in the application of the optimal control strategy and the tuning parameter search strategy of the control law.
