Abstract: This paper presents a model based concept for controlling the lift force of an airfoil, which depends on the angle of attack. This dependency holds a nonlinear behavior for angles of attack with separated flow. Such nonlinearity is modeled as a Wiener model. In order to output constant lift force, the Dynamic Matrix Controller using linearizing pre-compensation method is implemented. The control simulations performed in closed-loop with the software Ansys Fluent presented here significant results. The long term goal of this concept is to be used to control wind turbines airfoils, in order to increase the energy captured.
