A new design concept for a fully actuated unmanned surface vehicle

Abstract

To be effective in their roles, unmanned surface vehicles (USVs) need to be capable of performing a variety of distinct manoeuvres, including trajectory tracking and station keeping. Conventional fully-actuated actuator configuration permits an accurate station-keeping ability at the expense of the hydrodynamic efficiency which may be a critical factor for long-range high-speed operation. This paper presents a new USV design that is optimised for both manoeuvring styles. This attributes to the reconfigurable design that transforms between the under-actuated mode which suits high-speed operation and the fully-actuated mode which is effective for station keeping. In addition, the trimaran design offers wide deck space and great roll stability which is beneficial for a wide range of potential applications. The possible control system is also suggested for utilising multiple actuators that are equipped on the vehicle in the most energy efficient way. Regarding the simulation studies, the propose design has shown to enhance the station-keeping performance even when the USV is subjected to the sway disturbance.
