In this paper, a fuzzy logic controller is proposed for trajectory tracking of underwater-manipulator systems (UVMS). The controller is designed based on VD control method with gain tuning based on the fuzzy logic heuristics. The proposed fuzzy controller has the advantages that it does not require a model of the vehicle/manipulator system dynamics, and ensures robust performance in the presence of disturbances and dynamic interactions. In order to validate the effectiveness of the proposed controller, several simulations using a five degree of freedom UVMS are presented. The results show that the new controller provides robust performance of trajectory tracking in the presence of uncertainties about the dynamics and the hydrodynamic disturbances.
