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