Abstract[English]
The invention relates to controlling a wind turbine that has a tower and a rotor with a plurality of pitch-adjustable rotor blades. The invention involves obtaining a thrust force signal indicative of an estimation of thrust force experienced by the rotor, and obtaining a collective pitch offset signal for reducing oscillation of a top of the tower in a fore-aft direction of the wind turbine. The invention involves determining a gain based on the thrust force signal, applying the gain to the collective pitch offset signal to obtain a gain-adjusted collective pitch offset signal, and controlling the rotor blades in accordance with the gain- adjusted collective pitch offset signal.[French]
L'invention concerne la commande d'une éolienne qui présente une tour et un rotor avec une pluralité de pales de rotor à pas réglable. L'invention consiste à obtenir un signal de force de poussée indiquant une estimation de la force de poussée subie par le rotor, et à obtenir un signal de décalage de pas collectif pour réduire l'oscillation d'une partie supérieure de la tour dans une direction avant-arrière de l'éolienne. L'invention consiste à déterminer un gain sur la base du signal de force de poussée, à appliquer le gain au signal de décalage de pas collectif pour obtenir un signal de décalage de pas collectif à gain ajusté, et à commander les pales de rotor en fonction du signal de décalage de pas collectif à gain ajusté.
