| Outline of Final Research Achievements |
We considered a floating offshore wind turbine and investigated 1) performance improvement with wind speed preview, 2) design of an individual blade pitch controller, and 3) power maximization of wind farm. The outcomes of the study are summarized as follows: 1) we shed light on the relationship between the wind preview length and the control performance. 2) we proposed an individual blade pitch controller and tested its performance using a high-fidelity nonlinear simulator and 1/100 scale model with individual pitching capability. 3) power maximization of the wind farm was achieved by employing a distributed optimization scheme.

| Academic Significance and Societal Importance of the Research Achievements |
風車の大型化に伴い，ブレードピッチ角制御の重要性は増すと思われる。現在は，PIDベースの制御法が主流であるが，今後，LIDAR(レーザーを用いた遠隔計測装置）や個別ピッチを用いた高度な制御も用いられてくると予想される。本研究の成果は，そのような高度制御系を構成するために必要な基礎的な知見を与えるものである。
