Intelligent Control Strategies Implemented in Trajectory Tracking of Underwater Vehicles

AbstractUnderwater vehicle (UV) is a considerable technology for the renewable use of ocean resources. As we know, the ocean environment is harsh and complex and is affected by various force and moments. Hence, it is a tough task to attain an UV stable in the pre-planned static position and heading angle. Trajectory tracking control is a main research area for the above said problem. In this paper, various control strategies used in UVs for tracking control such as classical, robust, and intelligent controllers are reviewed. Intelligent controllers with novel controlling techniques give extreme good results under complex environmental uncertainties such as waves, ocean currents, and propulsion.KeywordsPID controlSliding mode controlAdaptive controlFuzzy controlArtificial neural networkLinear quadratic gaussianH infinityintelligent controllers
