Force actuated real-tme hybrid model testing of a moored vessel: A case study investigating force errors
Ueland, Einar Skiftestad; Skjetne, Roger; Vilsen, Stefan Arenfeldt (Journal article; Peer reviewed, 2018)This paper presents a study where real-time hybrid testing is used to emulate a moored barge. The barge is modelled physically while the mooring forces are simulated numerically and actuated onto the physical substructure. ... -
Force Tracking Using Actuated Winches with Position-Controlled Motors for Use in Hydrodynamical Model Testing
Ueland, Einar Skiftestad; Sauder, Thomas Michel; Skjetne, Roger (Peer reviewed; Journal article, 2021)In this paper, we consider the problem of accurate force control using actuated winches, intended for use in real-time hybrid hydrodynamic model testing. The paper is also relevant to other cable-driven parallel robot ... -
Numerical assessment of a double-acting offshore vessel's performance in level ice with experimental comparison
Su, Biao; Skjetne, Roger; Berg, Tor Einar (Journal article; Peer reviewed, 2014-10)In this paper a numerical model is used to investigate the level ice performance of a double-acting intervention vessel, and the results are compared with a limited set of experimental data. The icebreaking capability and ... -
Optimal Force Allocation for Overconstrained Cable-Driven Parallel Robots: Continuously Differentiable Solutions With Assessment of Computational Efficiency
Ueland, Einar Skiftestad; Sauder, Thomas Michel; Skjetne, Roger (Peer reviewed; Journal article, 2020)In this article, we present a novel method for force allocation for overconstrained cable-driven parallel robot setups that guarantees continuously differentiable cable forces and allows for small penalized errors in the ...
