Motion Modeling and Simulation of High-Speed Unmanned Surface Vehicle

According to the motion characteristic and the hydrodynamics of high-speed deep-V planings, forces and moments acted on a deep-V planing propelled by a contra-rotating propeller were analyzed, and on the basis of MMG modeling method, a real-time 6DOF mathematical motion model for the high-speed unmanned surface vehicle(USV) was built and the performance was simulated using the Matlab/Simulink software tool. Compared with the actual sea trial data, the results show that the proposed model can better reflect and simulate the maneuverability of the USV under ocean environment.
