Short summary

This paper provides a comparison of three well-established controllers. The benchmark considered is an airfoil section equipped with local control systems. The objectives are to track the blade lift set by the operator and to test its robustness when a perturbation arises. Differences between controllers are underlined in terms of needed effort and quality of the tracking.
