The paper is concerned with a reentry control problem in ocean drilling system with a flexible riser pipe. In the reentry operation, it is necessary to move the flexible riser pipe to a target position as fast as possible not to excite unstable vibration. Then there is a possibility to improve the control performance by scheduling control gains according to moving velocity, because the motion of flexible riser strongly depends upon the hydrodynamic drag force proportional to squared velocity. In the paper, a gain scheduling controller for an experimental model is designed using LPV (Linear Parameter Varying) control method. Then the effectiveness of the LPV control is shown through numerical simulation and model experiment.
