Codification of Good Seamanship in Complex and Congested Waterways
Yaqub Aris Prabowo, Peter Nicholas Hansen, Dimitrios Papageorgiou +1
This paper presents a novel method to quantify seafarers' good seamanship during navigation scenarios with multi-vessel encounters -- in open and confined waters --, and to compute…
Stochastic COLREGs Evaluation for Safe Navigation under Uncertainty
Peter Nicholas Hansen, Dimitrios Papageorgiou, Roberto Galeazzi +1
The encounter situation between marine vessels determines how they should navigate to obey COLREGs, but time-varying and stochastic uncertainty in estimation of angles of encounter…
Sliding Mode Control of Active Magnetic Bearings -- A Cascaded Architecture
Dimitrios Papageorgiou, Ilmar Santos
Accurate and robust positioning of rotor axle is essential for efficient and safe operation of high-speed rotational machines with active magnetic bearings. This study presents a c…
Autonomous Navigation in Confined Waters -- A COLREGs Rule 9 Compliant Framework
Peter Nicholas Hansen, Thomas T. Enevoldsen, Dimitrios Papageorgiou +1
Fully or partial autonomous marine vessels are actively being developed by many industry actors. In many cases, the autonomous vessels will be operating close to shore, and within…
Towards Prescribed Accuracy in Under-tuned Super-Twisting Sliding Mode Control Loops -- Experimental Verification
Dimitrios Papageorgiou
Obtaining prescribed accuracy bounds in super-twisting sliding mode control loops often falls short in terms of the applicability of the controller in high-performance systems. Thi…
A controller for reaching and unveiling a partially occluded object of interest with an eye-in-hand robot
Dimitrios Papageorgiou, Leonidas Koutras, Zoe Doulgeri
In this work, a control scheme for approaching and unveiling a partially occluded object of interest is proposed.The control scheme is based only on the classified point cloud obta…
