Robust fin/rudder ship roll stabilisation

Proceedings of IEEE International Conference on Control and Applications CCA-94, 1994
In ship operations the consequences of roll motions can seriously degrade the performance of mechanical and personnel effectiveness. Stabilising fins are used to alleviate these problems. Rudders, which have been extensively modified, have been used exclusively to stabilise roll.

Integrated robust ship roll stabilisation

International Conference on Control '94, 1994
The pernicious consequences of roll motions have a profound effect on the operational effectiveness of all types of ships. In warships the motions may be serious enough to curtail helicopter excursions from the deck, and degrade performance of the weapons systems and radars. Thus rendering the warship impotent to perform its designated role.

Energy-based Nonlinear Control of Ship Roll Gyro-stabiliser with Precession Angle Constraints

IFAC Proceedings Volumes, 2013
Abstract In this paper, we consider a passivity-based approach for the design of a control law of multiple ship-roll gyro-stabiliser units. We extend previous work on control of ship roll gyrostabilisation by considering the problem within a nonlinear framework. In particular, we derive an energy-based model using the port-Hamiltonian theory and then

Roll Motion of a Ship and the Roll Stabilising Effect of Bilge Keels

Journal of Navigation, 2008
The roll motion of a ship on waves is one of the six degrees of freedom and is the most difficult to predict since it deals with a motion similar to a spring-mass damper system, poorly damped by ship generated waves, in addition to the action of waves from the high seas.

A Note on the Applicability of Rudder Roll Stabilisation for Ships

1993 American Control Conference, 1993
This paper considers the question posed by ship operators and designers as to whether a Rudder Roll Stabilisation (RRS) system is justified for a particular ship, and aims to avoid the situation where a ship operator commissions an in depth study into the procurement of suitable hardware and software without being able to assess whether the approach is

Ship Roll Damping Using the Rudder and Stabilising Fins

IFAC Proceedings Volumes, 1992
Abstract The problem addressed is that of improving ship roll damping using the rudder and stabiliser fins in an integrated control configuration. Results from a digital computer simulation study are presented which demonstrate the enhanced roll damping which can be achieved by using control surfaces in concert.

Rudder Roll Stabilisation of Ships

2005
In this chapter, we present a case study of control system design for rudderbased stabilisers of ships using RHC. The rudder’s main function is to correct the heading of a ship; however, depending on the type of ship, the rudder may also be used to produce, or correct, roll motion.
