Design of ship dynamic positioning system based on fuzzy integral predictive control

This paper presents a ship dynamic positioning control method based on the fuzzy integral predictive controller. An integral controller is introduced to eliminate the steady state error, while a fuzzy control is adopted to provide satisifed control for uncertain systems, and a predictive control is used to solve constraint problem in the ship dynamic positioning, which can effectively reduce its energy consumption. The simulation results show that the proposed fuzzy integral predictive controller can meet the dynamic positioning requirements with the improvement of propulsion effciency and the reduction of thrust consumption.
