Stabilization of Parametric Roll Resonance with Active U-Tanks via Lyapunov Control Design of the fundamentals of control design for ship roll motion reduction. autopilots, dynamic.
Stabilisation of Parametric Roll Resonance the fin can be used to provide an active dynamic stabilization to roll motions. an overview of the fundamentals of control design for ship roll. The impact of control system design on ship performance has been significant in different applications of ship motion control: course keeping, station keeping, roll stabilisation and vertical motion/riding control, diving, path following, etc.
This monograph introduces ship motion control by studying the particular problems of control system design for course autopilots with rudder roll 5/5(1).
$\begingroup$ @ositivo: Not sure I understand fully the comment. If this is a jet not using a BF T/O, then you look at the group in the middle (5th and 4th curves from the left).
You know your T/O parameter, report it on the horizontal axis, find the projection onto the two curves, report the intersections onto the vertical axis. These parameters are subject to change as the following preliminary design parameter estimation is carried out.

SHIP ROLLING, ITS PREDICTION AND REDUCTION USING ROLL STABILIZATION. This paper is designed to provide the ship designer with a description of the phenomenon of ship rolling, its prediction using available theoretical methods and its reduction using available roll stabilization systems.
lqg autopilot and rudder roll stabilization control system design Roll stabilisation or reduction is to minimise the largest annular excursion of roll when a ship is subjected to wave disturbance. This is necessary to improve the comfort of personnel and the working efficiency of the crew on board.
Energy optimization is one of the key problems for ship roll reduction systems in the last decade. According to the nonlinear characteristics of ship motion, the four degrees of freedom nonlinear model of Fin/Rudder roll stabilization can be established.
This paper analyzes energy consumption caused by overcoming the resistance and the yaw, which is added to the fin/rudder roll stabilization Cited by: 3.

Therefore, according to the present proposal, the natural roll period of a ship in a natural seaway should be determined as follows: • The natural roll period shall be based on an artificial stability curve which is the average of the crest and trough righting lever curve in a reference Size: 1MB.

Yeah you could start with X-plane, which claims that it can figure out the flight characteristics from geometry parameters. It is based on laminar flow theory and on classic aeroplane shapes and configurations, but it is a start.
They have something called Plane Maker which could serve your. The book examines the role of computer simulation in improving waterway design, evaluates the adequacy of data input, explores the validity of hydrodynamic and mathematical models, assesses required and achievable accuracy of simulation results, and identifies research needed to establish shiphandling simulation as a standard design aid.
A single track vehicle can be stabilized and controlled by a variety of means. Controllers based on simplified dynamical models can potentially control more advanced linear and nonlinear models and/or real systems (i.e.
steer into the fall). The roll stabilization is the critical task, as path following can’t occur without roll control authority. Fig.5 shows the coherence between ship speed and peak period as a condition for resonance in the case TR=17s.
Here, parametric rolling can be expected when the ship is heading against waves with Tp =10s at a speed of Vs = kn. The Rolling Event Leg 3 of the Polarstern-Expedition ANT-XXV started on January 8 th in Capetown.

an interesting way to tackle the reduction of the roll induced by the swell. In general, controllers implemented in reality are PID-type. They are generally tuned at the ship roll frequency , , and ﬁnally designed with the use of optimisation. The dependance on ship speed is rarely described , but it may be assumed that the dependance.

attractiveness of the design approach is that it is based on closed-form solutions for plating and stiffeners in addition to representing the collision force as a design load in a relatively simplified manner. The procedure is demonstrated and verified by the design of a ship.Control Systems Engineering, 7th Edition has become the top selling text for this course.
