Stabilisation of ship roll motion via switched controllers
Ocean Engineering, 2012Abstract To control a ship motion for certain operating conditions, a particular controller may yield a most suitable performance. Therefore, a set of different types of controllers should be designed depending on various speeds, environmental and sea conditions so that appropriate controllers are selected in correspondence to these conditions.

A Method to Determine the Applicability of Rudder Roll Stabilisation for Ships
IFAC Postprint Volumes IPPV / International Federation of Automatic Control, 1993Abstract The problem addressed is that of assessing the suitability of Rudder Roll Stabilisation (RRS) for ships. This paper proposes a method whereby ship operators can assess the suitability of an RRS System for their ship and allows the operator to establish the benefits of incorporating such a roll stabilisation system prior to embarking on a ...

Extended radiated energy method and its application to a ship roll stabilisation control system
Ocean Engineering, 2013Large roll motions induced by sea waves can severely affect the ability of surface ships to perform their missions. The additional resistance caused by ship motions reduces ship speed, especially in moderate to high sea states. In addition, with increasing needs for energy savings and emissions reduction, the effect of added resistance on surface ship ...

Ship Gyroscopic Roll Stabilisation
Volume 5B: Ocean Engineering; Honoring Symposium for Professor Günther F. Clauss on Hydrodynamics and Ocean Engineering, 2022Abstract A thorough understanding of the interaction of waves with ships is a vital factor in the safe and economical technology design. Considerable advances have been made recently in the modelling of wave hydrodynamics and wave-structure interaction.

Robust fin roll stabilisation of surface ships
Proceedings of the 36th IEEE Conference on Decision and Control, 2002This paper details the design and implementation of a robust H/sub /spl infin// controller designed to stabilise the roll motion of a ship. The paper outlines the design of a classical PID controller in order that comparisons may be made between the performance of the two methods.
