Abstract
Gain-scheduled PI (GSPI) control has been widely acknowledged and used for a blade pitch controller for wind turbines. In this paper, we design an add-on H 2 preview compensator for floating wind turbines with the GSPI-based blade pitch controller. The preview information of the incoming wind speed is assumed to be available by LIDAR and the preview compensator is added to the existing GSPI controller. Simulation results show that the preview compensator is effective in reducing the fatigue loads of the blades and tower as well as fluctuations of the generator speed and platform motions.
