Model predictive control for floating offshore wind turbines with failure compensation using individual blade pitch control

In floating offshore wind turbines, the platform motions induced by wind and wave conditions should be reduced to mitigate fatigue load on wind turbine components and decrease cost efficiency. This paper considers an individual blade pitch angle control of floating offshore wind turbines using model predictive control (MPC) with failure compensation to improve controller performance in case of failure on a blade pitch actuator. The proposed MPC controller is demonstrated in numerical simulation using FAST, a high-fidelity aero-elastic simulator.
