Dynamic matrix control for dynamic positioning system of ships

This paper presents dynamic matrix control (DMC) for dynamic positioning (DP) system of ships with uncertain ship dynamics and unknown time-varying environmental disturbances. The presented controller is able to make the ship´s position and heading converge to the desired values. Any a priori knowledge of the ship dynamics and disturbances isn´t required in our control design. Simulation studies on a dynamically positioned ship are carried out and the simulation results illustrate the effectiveness of our proposed control scheme.
