영문 초록

In ship operation. the roll motions can seriously degrade the performance of mechanical and personnel effectiveness. So many studies for the roll stabilization system design have been performed and good results have been achieved. In many studies, the stabilizing fins are used. Recently rudders. which have been extensively modified. have been used exclusively to stabilize the roll. But. in the roll stabilization control system. the control performance is very sensitive to the ship speed. So. we can see that it is important to consider the ship speed in the rudder roll control system design. The gain-scheduling control technique is very useful in the control problem incorporating time varying parameters which can be measured in real time. Based on this fact. in this paper we examine the H∞ -Gain Scheduling control design technique. Therefore. we assume that a parameter. the ship speed which can be estimated in real time. is varying and apply the gain-scheduling control technique to design the course keeping and anti-rolling control system for a ship. In this control system. the controller dynamics is adjusted in real-time according to time-varying plant parameters. The simulation result shows that the proposed control strategy is shown to be useful for cases when the ship speed is varying and robust to disturbances like wind and wave.
