Summary:We show how an efficient nonlinear controller for a general model
of autonomous underwater vehicles (AUVs) dynamics, with uncertainties
and external disturbances, can be designed by means of Lyapunov
techniques. The control task we consider consists of tracking a given
reference trajectory. As part of the design strategy, both model
uncertainties and external disturbances physically corresponding to the
effect of an underwater current are represented as a bounded
perturbation of a nominal model of the vehicle dynamics
