Upravljanje vjetroagregatom korištenjem linearizacije u povratnoj vezi
Potreba razvijanja naprednih sustava upravljanja brzinom vrtnje i snagom vjetroagregata raste s povećanjem dimenzija vjetroagregata. Zbog nelinearne dinamike vjetroagregata, korištenjem nelinearnih metoda sinteze upravljanja moguće je poboljšati sustav upravljanja vjetroagregatom. U radu je implementirano nelinearno upravljanje pomoću linearizacije u povratnoj vezi za radno područje gdje je cilj upravljanja optimizacija generirane snage. Ponašanje sustava s razvijenim upravljanjem pomoću linearizacije u povratnoj vezi uspoređena je s ponašanjem sustava upravljanog PI regulatorom te je tako potvrđena ispravnost implementiranog upravljačkog algoritma. Upravljanje pomoću linearizacije u povratnoj vezi moguće je poboljšati ako se prilikom sinteze regulatora uzmu u obzir fizička ograničenja sustava.
Due to increase of dimensions of wind turbine, its speed and power control needs to develop further. Because of non-linearities in a wind turbine system, the use of non-linear model-based controllers has a potential to improve the overall system performance. This thesis deals with the development of a nonlinear control scheme based on feedback linearization for the wind region where power optimization strategy is applied. The behaviour of the system with designed controller is compared to the one with a commonly used PI controller. Improvements in feedback linearization control performance can be achieved if physical constraints of the system were taken into account in the control design process.
