Abstract: A robust trajectory control problem for an underactuated AUV with parameter uncertainties and external disturbances was considered. The trajectory control was decomposed in the horizontal plane and vertical plane. Based on the robust theory, the AUV model for heading control was proposed, and the heading controller was designed. The simulated results show that the method can effectively overcome disturbances of constant ocean currents to ensure the precision track.

Abstract: To expand the working field of AUV, a kind of underwater docking technology of AUV with the dock is introduced which has an acoustic short baseline positioning system and visual guiding system. The short baseline system can guide the AUV to implement long range navigation. And the visual guiding positioning system can guide the AUV’s underwater close docking. To get intuitive demonstration on surface workstation, the virtual simulation module using creator and Vega Prime software was developed. Through pool experiments, it shows that the docking mode is feasible and the simulation is intuitive, effective.
