In this paper, active structural control design of the OC3-Hywind floating wind turbine is investigated to reduce platform oscillation and fatigue load. Firstly, a non-linear dynamic model for system surge-heave-pitch motion is established based on the first principle. Secondly, system identification is performed in order to verify the effectiveness of the proposed model, and it is then simplified into a linear form to facilitate control design. Thirdly, multi-objective controller with guaranteed cost and poles assignment is designed. Finally, we analyze the simulation results and give conclusions.
