Wind energy is recognized worldwide as cost-effective and environmentally friendly and is among the fastest-growing sources of electrical energy.

To further decrease the cost of wind energy, wind turbines are being designed at ever-larger scales, which is challenging due to greater structural loads and deflections. Large-scale systems such as mordern wind turbines increasingly require a control co-design approach, whereby the system design and control design are performed in a more integrated fashion. We will overview a two-bladed downmind morphing rotor concept that is expected to lower the cost of energy at wind turbine sizes beyond 13MW compared to continued upscaling of traditional three-bladed upwind rotor designs. We will describe an aero-structural-control co-design process that we have used in designing such extreme scale wind turbines. We will also highlight some of the control systems issues for wind turbines at these scales and outline an advanced control method we are developing to address these issues. Finally, we will show selected experimental results from our 2019-2020 fiels-testing campaign of a gravo-aero-elastically scaled version (with 21-meter blades) of the two-bladed downwind morphing rotor concept at the US National Renewable Energy Laboratory’s (NREL’s) National Wind Technology Center. We shall close by discussing continuing challenges and on-going and future research avenues that can further facilitate the growth of wind energy.
