Opis:: The paper shows purposefulness and possiblity of automation of ship propulsion systems, especially those of POD type, intended to be used on four Baltic navigation ships: a containership, ro-ro ship, product tanker, as well as river-sea-going ship, designed within the frame of the Eureka "Baltecologicalship" project. Requirements of ship classification societies, and general ones for modern ship control systems were presented, as well as a review and analysis of currently applied power plant automation systems for diesel- electric ships fitted with podded propulsion drive (POD), were performed. Moreover real ways and possibilities of controlling ship s course and speed were indicated. Information contained in this paper may facilitate selecting appropriate design assumptions for a propulsion control system to be applied on the above mantioned ships.

Opis:: This paper presents a cascade system which stabilizes the transverse deviation of the ship in relation to the set path. The ship’s path is determined as a broken line with specified coordinates of way points. Three controllers are used in the system. The primary controller is the trajectory controller. It generates the set value of heading for the course control system or angular velocity for the turning control system. The course control system is used on the straight line of the set trajectory while the turning controller is used during a change of the set trajectory segment. The characteristics of the nonlinear controllers are selected in such a way that the properties of the control system with the rate of turn controller are modelled by the first-order inertia, while the system with the course keeping controller is modelled by a second-order linear term. The presented control system was tested in Matlab-Simulink environment. The results of tests performed on a lake are presented and discussed.

Opis:: Marine navigation consists in continuous observation of the situation at sea, determination the anti-collision manoeuvre. So it necessary to determine ship safe trajectory as a sequence of ship course changing manoeuvres. Each manoeuvre is undertaken on the basis of information obtained from the anti-collision system ARPA. This paper describes a method of safe ship control in the collision situation in a fuzzy environment based on a branch and bound method and a genetic algorithm. The optimal safe ship trajectory in a collision situation is presented as multistage decision-making process.

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:: This paper presents the designs of two observers, which are: the extended Kalman filter and the nonlinear passive observer. Based on the measured values of ship position and heading, the observers estimate the surge, sway and yaw velocities of the ship motion. The observers make use of the simplified nonlinear mathematical model of ship motion in which the neglected ship dynamics and disturbances are modelled using bias. The designed observers firstly have been simulated on a computer model where their parameters were calibrated, and then were implemented on the physical model of the training ship “Blue Lady” in the ship handling centre in Ilawa-Kamionka. The comparative analysis was done with respect to the estimated variables describing the ship motion in three directions: surge, sway and yaw.

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:: This paper presents an application of selected methods of optimal and game control theory to determine own ship safe trajectory when passing other ships encountered in good and in restricted visibility at sea. Five algorithms for determining safe trajectory of the own ship in a collision risk situation: non-cooperative positional game, non-cooperative matrix game, cooperative positional game, dynamic optimization, and kinematic optimization are compared. The analysis is illustrated with examples of computer simulations of the algorithms to determine safe and optimal own ship trajectories in the real navigational situations at sea.

Opis:: This work analyzes the sensitivity functions and optimum control of a transport and logistics process model. It explains the fundamental model of controlling safe ship movement as a differential game, and optimizing control algorithms through multi-matrix game and multi-stage positioning game. The sensitivity features for controlling safe ship in actual collision scenario are described in relation to inaccurate information of process position and variations in its varables, based on the determination of computer simulation algorithms in Matlab/Simulink software.
