The control strategy combined input from turbine states (rotor speed, rotor azimuth, each blade pitch) with inflow angle measurements (each blade angle of attack at station 11 of 15) to derive blade pitch demand sugnals. The controller reduced loads suffficiently to allow a 10% rotor extension and reduce COE by 6.3%.\u003cbr\u003e\u003cbr\u003e\u003cb\u003eAuthor:\u003c\/b\u003e National Renewable Energy Laboratory (Nr\u003cbr\u003e\u003cb\u003eISBN-10:\u003c\/b\u003e 1249175666\u003cbr\u003e\u003cb\u003eISBN-13:\u003c\/b\u003e 9781249175667\u003cbr\u003e\u003cb\u003ePublisher:\u003c\/b\u003e Bibliogov\u003cbr\u003e\u003cb\u003eLanguage:\u003c\/b\u003e English\u003cbr\u003e\u003cb\u003ePublished:\u003c\/b\u003e 07\/21\/2012\u003cbr\u003e\u003cb\u003ePages:\u003c\/b\u003e 130\u003cbr\u003e\u003cb\u003eFormat:\u003c\/b\u003e Paperback\u003cbr\u003e\u003cb\u003eWeight:\u003c\/b\u003e 0.54lbs\u003cbr\u003e\u003cb\u003eSize:\u003c\/b\u003e 9.69h x 7.44w x 0.28d","brand":"National Renewable Energy Laboratory (Nr","offers":[{"title":"Paperback","offer_id":47611122843903,"sku":"9781249175667","price":20.75,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0662\/2982\/9887\/files\/img_650b2bd9-e448-4afb-ab5b-f3bb0d6e36a9.jpg?v=1764511876","url":"https:\/\/www.whiterainbookhouse.com\/products\/low-wind-speed-turbine-project-national-renewable-energy-laboratory-nr-9781249175667","provider":"WR Book House","version":"1.0","type":"link"}
