Opis:: Improving the performance of Dynamic Positioning System in such applications as station keeping, position mooring and slow speed references tracking requires improving the position and heading control precision. These goals can be achieved through the improvement of the ship control system. Fractional-order calculus is a very useful tool which extends classical, integer-order calculus and is used in contemporary modeling and control applications. Fractional-order PI?D? controller, based on the added flexibility of fractional-order operators, are capable of superior performance compared to their integer-order counterparts. This paper presents the fractional order PI?D? controller designed to maintain the ship position and heading and the results were compared with classical integer order PID controller.

Opis:: One of the crucial systems of sea mining ship for poly-metallic concretions is its motion control system (SMC). Power of such system depends on sea environment characteristics and main dimensions of the ship. It can be expected that it will have important influence on total power of the ship’s power plant and in effect on the mining ship’s dimensions. In this paper is presented one of the possible ways of preliminary estimation of design power of SMC system for sea mining ship. Since details of design solution of such system for the ship in question are unknown (ships of the kind have not been built so far) the presented results should be considered to be the first estimation of the order of the power demand.

Opis:: Advances in computer systems and innovative technologies along with their implementation into the shipping industry not only enabled efficient data exchange between the ship and the shore, but also created a single integrated information network linking all participants of the process and all elements of the maritime sector. Development of the concept of autonomous ships and automated control facilities for their functionality became the next stage in the evolution of innovations. The process of software adaptation, additional electronic steering systems, optical and digital means of monitoring as well as satellite communication facilities for autonomous ships are among the tasks which require search and development of the solutions. Provision of reliable and safe functioning of such ships in the autonomous mode requires development of models and methods for ensuring their accident-free navigation both in relation to the process of ships divergence and improvement of automatic steering systems of movement and course steadiness. In the given work, the analysis of realization of the crewless navigation and possibility of ship automatic movement control systems advancement on the basis of application of mathematical model for the purpose of enhancement of process of the autonomous ship steadiness on the set course is proposed.

Opis:: The use of new energy generation technologies such as solar energy and electric propulsion technologies to form integrated power propulsion technology for ships has become one of the most concerned green technologies on ships. Based on the introduction of the principles and usage patterns of solar photovoltaic systems, the application characteristics of solar photovoltaic systems and their components in ships are analyzed. The important characteristics of the marine power grid based on solar photovoltaic systems are explored and summarized, providing a basis for future system design and application. Photovoltaic solar cells are made using semiconductor effects that convert solar radiation directly into electrical energy. Several such battery devices are packaged into photovoltaic solar cell modules, and several components are combined into a certain power photovoltaic array according to actual needs, and are matched with devices such as energy storage, measurement, and control to form a photovoltaic power generation system. This article refers to the basic principle and composition of the land-use solar photovoltaic system, and analyzes the difference between the operational mode and the land use of the large-scale ocean-going ship solar photovoltaic system. Specific analysis of large-scale ocean-going ship solar photovoltaic system complete set of technical route, for the construction of marine solar photovoltaic system to provide design ideas.

Opis:: The paper reports the design and tests of the planar autopilot navigation system in the three-degree-of-freedom (3-DOF) plane (surge, sway and yaw) for a ship. The aim of the tests was to check the improved maneuverability of the ship in open waters using the improved nonlinear control algorithm, developed based on the sliding mode control theory for the ship-trajectory tracking problem of under-actuated ships with static constraints, actuator saturation, and parametric uncertainties. With the integration of the simple increment feedback control law, the dynamic control strategy was developed to fulfill the under-actuated tracking and stabilization objectives. In addition, the LOS (line of sight) guidance system was applied to control the motion path, whereas the sliding mode controller was used to emulate the rudder angle and propeller rotational speed control. Firstly, simulation tests were performed to verify the validity of the basic model and the tracking control algorithm. Subsequently, full scale maneuverability tests were done with a novel container ship, equipped with trajectory tracking control and sliding mode controller algorithm, to check the dynamic stability performance of the ship. The results of the theoretical and numerical simulation on a training ship verify the invariability and excellent robustness of the proposed controller, which: effectively eliminates system chattering, solves the problem of lateral drift of the ship, and maintains the following of the trajectory while simultaneously achieving global stability and robustness.

Opis:: The dynamical positioning system is a complex control consisting of a number of components, including: filters, observers, controllers, and propeller allocation systems. The design and preliminary analysis of operational quality of system operation are usually done based on numerical simulations performed with the aid of the mathematical model of the ship. The article presents a concept of the dynamic positioning system applied to steering the training ship Blue Lady used for training captains in the ship handling research and training centre owned by the Foundation for Safety of Navigation and Environment Protection in Ilawa/Kamionka. The simulation tests performed in the numerical environment of Matlab/Simulink have proved the usability of the designed system for steering a ship at low speed.

Opis:: The paper introduces algorithm for determining the relative positions of two ships manoeuvring as a pair. This algorithm also takes into account determination of angle ă, which is difference between present approaching vessel and guidance vessel course. Relative positioning system is a vision system based on three colours LEDs matrix and rotating CCD camera. There are presented ways of distance calculation based on photogrammetric methods from the known distance between the characteristic points of the real. Several possible cases are taken into account. The considerations have been illustrated on the basis of model of the system. These results confirm the correctness of the operation of the algorithm that is used by the designed measuring system.

Opis:: The article presents an original adaptive ship course-keeping system. The control algorithm is based on a knowledge base. Its integral part - a computer ship movement dynamical model - uses a set of signals obtained from the object’s input and output. In this way we avoid problems arising while designing classical control algorithms for a complex, non-linear ship model. Approximators utilizing base functions of the model are used for model adaptation. The presented methodology is general as it can also be applied in other ship control tasks or to other dynamic objects. The proposed intelligent course-keeping system has been verified by simulation.
