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 ...
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 ...
