This paper proposes a new type of Tuned Liquid Column Damper (TLCD)
for vibration suppression of a semi-submersible offshore wind turbine. The
proposed mechanism consists of three columns of liquid equipped with three
valves that allow the liquid to transfer between columns. The nonlinear
dynamic model of the offshore wind turbine and the TLCD is derived and
validated. The model is linearized around equilibrium point and a mixed H
- Velocity Based Ground-hook (VBG) controller is designed to suppress
vibrations of the platform and achieve the rated rotor speed. The
performance of the controllers is investigated through numerical
simulations.
