Mathematical modeling and fuzzy proportional–integral–derivative scheme to control the yaw motion of a wind turbine

open access: yesWind Energy, 2021
In this paper, we present a mathematical model and control strategy to regulate the yaw of a horizontal axis wind turbine. In order to obtain the dynamic equations of the yaw motion, the mathematical model is developed using the Euler–Lagrange ...
