Abstract: This paper presents platform position control of utility-scale floating offshore wind turbines in surge and sway directions using aerodynamic thrust force. The position control will be useful in mitigating the wake effect, and thus maximizing the total power capture, of an offshore wind farm. A linear-quadratic-integrator (LQI) controller is designed to achieve the control objectives of platform position transfer to a specified position for the wake loss mitigation, as well as of platform position regulation against disturbances in wind and wave. Power regulation during and after the position transfer is accomplished by the standard constant-power strategy. It is demonstrated, through simulations of a 5-MW wind turbine in the FAST software, that the LQI controller can attain satisfactory platform position transfer and regulation.
