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 ... -
Comparing Combinations of Linear and Nonlinear Feedback Terms for Ship Motion Control
Sørensen, Mikkel Nørgaard; Breivik, Morten; Skjetne, Roger (Peer reviewed; Journal article, 2020)In this article, combinations of linear and nonlinear feedback terms are investigated for 3 degrees-of-freedom pose and velocity control of ships. Nonlinear control algorithms that are found in the literature often have ... -
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 ...
