Offshore exploration and exploitation of hydrocarbons have opened up an era of
dynamically positioned (DP) vessels. DP control systems maintain floating structures in fixed …

This article presents a unified state-space model for ship maneuvering, station-kee**, and
control in a seaway. The frequency-dependent potential and viscous dam** terms, which …

The technology of hydrodynamic modeling and marine craft motion control systems has
progressed greatly in recent years. This timely survey includes the latest tools for analysis …

Vessel dynamic positioning (DP) systems are based on conventional PID-type controllers
and an extended Kalman filter. However, they present a difficult tuning procedure, and the …

It is generally assumed in dynamic positioning of over-actuated marine vessels that the
control effectiveness matrix (input matrix) is known and constant, or, in case of fault …

The capability of following a moving target in an environment with obstacles is required as a
basic and necessary function for realizing an autonomous unmanned surface vehicle (USV) …

This talk starts with the early history of ship autopilot design including the history and
invention of the gyroscope and the celebrated “three-term-controller” which today is known …

This dissertation contains new results on the design of dynamic positioning (DP) systems for
marine surface vessels. A positioned ship is continuously exposed to environmental …

This paper presents a station kee** control method for underactuated unmanned surface
vehicles (USVs) to resist environmental disturbances with unknown magnitude and …

This paper addresses structural issues in the design and operation of marine control
systems on ships and offshore installations. In particular, control systems for offshore vessels …
