• A Dynamic Window-Based Controller for Dynamic Positioning Satisfying Actuator Magnitude Constraints 

      Sørensen, Mikkel Nørgaard; Lyngstadaas, Ole Nikolai; Eriksen, Bjørn-Olav Holtung; Breivik, Morten (Journal article, 2018)
      This paper considers the use of a simplified dynamic window (DW) algorithm to handle actuator magnitude constraints for a 3 degrees-of-freedom dynamic positioning controller for ships. To accomplish this, we use the ...
    • Improvement of Ship Motion Control Using a Magnitude-Rate Saturation Model 

      Lyngstadaas, Ole Nikolai; Sæterdal, Tore Egil; Sørensen, Mikkel Nørgaard; Breivik, Morten (Chapter, 2018)
      Motion control concepts for ships have traditionally not focused on handling actuator constraints. This paper investigates the effects on performance of a pair of nonlinear control schemes by developing and implementing a ...
    • Ship Motion Control Concepts Considering Actuator Constraints 

      Lyngstadaas, Ole Nikolai (Master thesis, 2018)
      Numerous motion controllers and autopilots have been proposed over the years. Most control algorithms found in the literature do not explicitly consider saturation constraints for the actuators. In traditional control ...
