An adaptive fuzzy gain auto-pilot for ship track-keeping is developed. This auto-pilot is composed of Sugeno fuzzy type auto-pilot in an ordinary feedback loop and adjustable scaling factors mechanism in an additional feedback loop. The adjustment mechanism represents a fuzzy controller that changes scaling factors of the base fuzzy auto-pilot. The control system for the track-keeping is completely described. For the track-keeping problem, the maneuver of way-point turning and ship guiding through a complex path (trajectory) are presented. The influence of sea current and wave disturbances on track-keeping performance was also considered. Simulation results obtained by the Sugeno fuzzy type auto-pilot are first presented. Then, those results are compared with ones obtained by an adaptive fuzzy auto-pilot.
