Resumen:
Abstract– In this paper the adequacy of interpolation based approaches to describe highly perturbed complex dynamics in discrete time (like ROVs and AUVs) is analyzed.The analysis establishes features, particularly of Adams- Bashforth approximations, related to accuracy in marked disturbed contexts with noisy measurements. Moreover, a detailed study of the sensitivity of local prediction errors under a high signal-to-noise ratio is carried out with analyticalexpressions in dependence of physical coefficients of the vehicle like inertia, drag, buoyancy and maneuver parameters. The results are subsequently illustrated with numerical simulations.
