LPV Hydrodynamic Controller for a 15MW Floating Offshore Wind Turbine

Research output: Chapter in Book/Report/Conference proceedingArticle in proceedingsResearchpeer-review

Abstract

This work investigates a Floating Offshore Wind Turbine FOWT collective blade pitch controller aimed to reduce platform pitching and enhance generator power production. The work incorporates both, hydrodynamic state estimates and structural states in a Linear Parameter Varying LPV controller. The controller design is based on linearised state space models of the wind turbine aided by OpenFAST, a high-fidelity wind turbine simulator. Method testing was on a full-order nonlinear model of the 15MW FOWT via OpenFAST using turbulent wind speed and an irregular wave disturbance. Compared to previous published work, the generator power and platform pitching RMSEs were reduced by 13% and 37%, respectively.
