Dynamic matrix control for dynamic positioning system of ships

Abstract

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.
