対外乱特性を利用した船舶の推力低減化位置制御

抄録

The Dynamic Positioning System(DPS) of a ship is evaluated by the capability to keep the position against the external disturbances as an important performacne index. Captains or DPS operaters usually decide the suitable heading direction while watching the thrust vectors producing to keep the position. In this paper, we present a DPS with an auto-turning function which automate such operations needed for experiences. The design strategy of the controller is derived by the stability in the sense of Lyapunov and L₂-gain performance analysis.
