- W4353066693 abstract "<strong class=journal-contentHeaderColor>Abstract.</strong> We assess the performances of two control strategies on the IEA 15 MW reference floating wind turbine through<br />OpenFAST simulations. The multivariable feedback controller tuned by the toolbox of the Reference Open Source Controller<br />(ROSCO) is considered the benchmark for comparison. We then tune the feedback gains for the multi-variable controller,<br />considering two cases: with and without lidar-assisted feedforward control. The tuning process is performed using OpenFAST<br />simulations considering realistic offshore turbulence spectral parameters. We reveal that the optimally tuned controllers are<br />robust to changes in turbulence parameters caused by atmospheric stability variations. Compared to the baseline multivariable<br />controller, the one with optimal tuning significantly reduced the tower damage equivalent load, which results in a lifetime<br />extension of 19.2 years. With the assistance of feedforward control provided by a typical four-beam lidar, compared with the<br />optimally tuned MVFB control, the lifetime of the tower can be extended by 5.1 years." @default.
