    • Automatic touch-up of welding paths using 3D vision 

      Njåstad, Eirik Bjørndal; Egeland, Olav (Journal article; Peer reviewed, 2016)
      This paper presents a system for automatic robotic welding based on offline programming using CAD data. The welding paths are corrected before execution with 3D vision where the 3D image is aligned with the CAD model of ...

    • Experimental results of Discrete Time Variable Structure Control for Dynamic Positioning of Marine Surface Vessels 

      Raspa, Paolo; Benetazzo, F.; Longhi, S.; Ippoliti, G.; Sørensen, Asgeir Johan (Journal article, 2013)
      This paper presents a Discrete-Time Variable-Structure Control (DTVSC) for the dynamic positioning system of a marine supply vessel to guarantee robustness with respect to disturbances and parametric variations. The control ...

    • A fuzzy approach to robust Social Sustainability Assessment (ISSA) 

      Akbarinejad Khamene, Tahmineh; Barahmand, Zahir; Temeljotov Salaj, Alenka (Journal article, 2023)
      Social sustainability has been increasingly recognized as a fundamental component of sustainable development in recent years. It is still challenging to measure social sustainability in comparison to other dimensions of ...

    • Integration Filter for APS, DVL, IMU and Pressure Gauge for Underwater Vehicles 

      Dukan, Fredrik; Sørensen, Asgeir Johan (Journal article, 2013)
      High-accuracy underwater navigation is important in order to automate motion control of remotely operated vehicles (ROVs). An observer that estimates the vehicle states (position, velocity, attitude and turn rates) is ...

    • Model Predictive Control of a Kaibel Distillation Column 

      Kvernland, Martin Krister; Halvorsen, Ivar J.; Skogestad, Sigurd (Journal article; Peer reviewed, 2010)
      This is a simulation study on controlling a Kaibel distillation column with model predictive control (MPC). A Kaibel distillation column has several advantages compared with conventional binary column setups. The Kaibel ...

    • Observer design for underwater vehicles with position and angle measurement 

      Refsnes, Jon E Gorset; Pettersen, Kristin Ytterstad; Sørensen, Asgeir Johan (Journal article, 2006)
      In this paper we propose a new observer system for underwater vehicles. The main design objective behind this strategy is to reduce the destabilizing effect of the Coriolis and centripetal forces and moments in the observer. ...

    • Simulator and Control System Design for a Free Floating Surface Effect Ship at Zero Vessel Speed 

      Auestad, Øyvind Fidje; Gravdahl, Jan Tommy; Sørensen, Asgeir Johan; Halvorsen, Trygve Espeland (Journal article; Peer reviewed, 2013)
      This paper covers vertical motion damping of a free floating Surface Effect Ship (SES) at zero vessel speed. Vertical motion damping is requested at the bow deck of the SES during offshore wind turbine docking operation. ...

    • Trajectory Tracking Motion Control System for Observation Class ROVs 

      Fernandes, Daniel de Almeida; Sørensen, Asgeir Johan; Donha, Decio C. (Journal article, 2013)
      This paper proposes a MCS (Motion Control System) with trajectory tracking capability for observation class ROVs (Remotely Operated Vehicle) used to carry out automated high-resolution image capturing missions, e.g. ...

    • Weather optimal dynamic positioning of underactuated AUVs using output feedback control 

      Refsnes, Jon E Gorset; Sørensen, Asgeir Johan; Pettersen, Kristin Ytterstad (Journal article, 2006)
      In this paper we present an output feedback control system for dynamic positioning of underactuated AUVs. The control objective is to maintain a desired distance to the target while orienting the vehicle towards the target ...
