Floating offshore wind turbines have attracted attention recently. In this paper, we design a blade pitch angle controller by H∞ preview control. This control law uses wind speed preview information. We investigate the performance of controllers with and without consideration for uncertainty on the preview information and discuss the suitable preview length in terms of H∞/H2 norm and wind turbine's control objective.
