Simulation of ship's maneuvering motion under the effect of ship-ship interaction

To study the ship's maneuvering motion better under the effect of ship-ship interaction,this paper adopted the idea of MMG modeling and a group of general formulas of force and moment for ship-ship interaction were used.Based on above,the ship control operated by rudder was studied under the effect of ship-ship interaction combining with the PD heading control and the underactuated track control algorithms,and simulation was carried out by using Matlab.Results show that the effect of ship-ship interaction on ship's maneuvering motion can be controlled by rudder under certain conditions.
