Abstract

Fremgangsmåte for styring av vindturbintårnlast. Rotorbladenes angrepsvinkel styres på konvensjonelt vis ved hjelp av en kollektiv kommandokomponent. En estimator estimerer tårnresonansakselerasjonen og trippel-per-omdreining bladubalanseakselerasjon. Kombineringslogikk, forbundet med den estimerte resonansakselerasjonen og den estimerte trippel-per-omdreining akselerasjonen (3P) akselerasjonen gir en kombinert angrepsvinkelmodulasjon for å dempe tårnresonansbevegelsen og trippel-per-omdreining bevegelsen ved bruk av kollektiv modulasjon. Angrepsvinkelmodulasjonen kombineres med kollektiv kommando komponenten for 'a drive angrepsvinkelaktuatorene.
