The paper is concerned with the dynamic positioning control of a moored floating platform model. Moorings are used to maintain the position of the platform against quasi-constant external forces induced by current and wind. The control purpose is to suppress the slow drift oscillation due to drifting force in irregular waves using thrusters so that they do not respond to the linear exciting force in the wave frequency range. Control of motions in the wave frequency region has to be ignored because the amplitude of those motions is smaller than that of the slow drift oscillation and enormous thruster power is needed to control them. The problem was formulated in the framework of H control, was solved using the LMI (linear matrix inequalities) Control Toolbox on Matlab. Model experiments in oblique incident waves were carried out and some successful results are shown.
