Abstract: The presented multiple underwater vehicle simulation system(MUVSS) is a distributed real-time digital simulation system that is used for the demonstration of the control architecture,cooperative control,path planning,learning algorithm of multiple underwater vehicle system(MUVS).The system will be the base and effective method for the development of multiple underwater vehicle technology.This paper discusses the ways to implement MUVS simulation by using the distributed simulation technology cased on LAN,and presents the hardware and software of the system in detail.
