Autonomous underwater vehicles (AUVs) have broad applications owing to their small size,
low weight, strong ability to operate autonomously, and ability to replace humans in …

This paper proposes a fractional-order sliding mode control method for an underactuated
autonomous underwater vehicle (AUV) with random disturbances. First, a new fractional …

In this paper, a novel interval type-2 fuzzy fractional order super twisting algorithm
(IT2FFOSTA) which is essentially a second order sliding mode controller is presented. The …

Mobility and controllability of a deep ocean mining vehicle directly determine its operational
efficiency and safety. In this study, the spatial hydrodynamic distributions acting on a mining …

A dynamic model of a remotely operated vehicle (ROV) is developed. The hydrodynamic
dam** coefficients are estimated using a semi-predictive approach and computational …

Aiming to solve the tracking control problem of a class of second-order underactuated
mechanical systems with unknown model parts, external disturbances and noise …

This article investigates the trajectory tracking control problem for unmanned surface vessels
with input saturation and full-state constraints. The barrier Lyapunov function is used to solve …

In this paper application of a nonlinear tracking control algorithm for dynamics testing of
underwater vehicles is presented. The controller, suitable for fully actuated vehicles, is …

Disturbance observer-based control allows to compensate unknown inputs, however, in
most cases, requiring their integer-order differentiability. In this paper, a novel disturbance …

The open-frame structure of work-class ROVs results in significant model uncertainties, and
its motion is strongly disturbed by the umbilical cable. To address these problems, this article …
