Abstract
Artificial Intelligent(AI), which is called one field of science, has rapidly been developed during the last half century. It has been applied to a variety industry development. One of the new popular applications is "automatic navigation", operated without man's handling. A scope of automatic navigation was expanded into airplane, car and ship that needed speedy and correct operation[1][4][10][11].


This paper presented automatic navigation of ship using fuzzy control system in dynamic sea environment. In deep sea, because limitation of place doesn't exist, the need of automatic navigation for obstacle avoidance is a little. However in near sea, the need of automatic navigation for obstacle avoidance is big because of many obstacles (i,e., big and small island, working or moving ship, etc.). Therefore this paper used multivariable fuzzy control system for more safe and automatic navigation.


Multivariable fuzzy control system consist of two subsystems with three inputs and three outputs. Thus it is navigated at five maps. Simulation and plotting graph are found that they had satisfactory results. Therefore, ship using multivariable fuzzy control system was confirmed that it could avoid obstacle in dynamic environment and safely navigate in near sea by itself.
