Design of an Underactuated USV Catamaran

2022
The Sea2Future program was developed at ENIDH, since 2018, and it has involved the construction of an unmanned surface vehicle (USV) with the participation of students and teachers of this educational institution. This firstUSV, with two hulls, referred to as USV-enautica1, included a control system which allows it to carry out several functions ...

The control and simulation for the ADRC of USV

2015 Chinese Automation Congress (CAC), 2015
The system of unmanned surface vehicle has the problems of large inertia, long time-lag. nonlinearity and the difficulty of building accurate models. Furthermore it can easily be interfered by external factors, such as wind, wave and airflow. The traditional way of controlling, PH), which is applied by this system, can hardly work well to control the ...
