| Abstract: |
| Based on conceptual design of FDPSO-TLD,a dynamic model of TLD system is derived.For the purpose of reducing axial dynamic response of the riser,H∞ control method is employed to develop a winch which can compensate the heave motion of the hull.H∞ controller and H∞ observer are designed for active control of axial dynamic stress of the riser.The simulation results in frequency domain and time domain show that the proposed control method is effective and feasible if the parameter of H∞ controller is appropriately selected. |
