(Chapter, 2019)This paper presents a comparative eigenvalue analysis of the stability characteristics and small signal dynamics of four different control strategies for Synchronous Machine Emulation (SME) by power electronic converters, ... -
Comparative Evaluation of Virtual Inertia and Fast Frequency Reserve Provided by HVDC Terminals
(Chapter, 2022)This paper compares the impact on power system frequency transients from virtual inertia and Fast Frequency Reserve (FFR) provided by HVDC converters. Specifically, frequency nadir, Rate-of-Change-of-Frequency (RoCoF), and ... -
A Comparative Study of Sparsity Promoting Techniques in Neural Network for Modeling Non-Linear Dynamics
(Journal article; Peer reviewed, 2023)Sparsity-promoting techniques show promising results in improving the generalization of neural networks. However, the literature contains limited information on how different sparsity techniques affect generalization when ... -
Comparing Combinations of Linear and Nonlinear Feedback Terms for Motion Control of Marine Surface Vessels
(Journal article; Peer reviewed, 2016)Nonlinear control algorithms are often designed with linear feedback terms. Such linear feedback typically gives rise to nice exponential stability properties, but are not physically realistic since all actuators have ... -
Comparing Combinations of Linear and Nonlinear Feedback Terms for Ship Motion Control
(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 ... -
Comparing Controllers for Dynamic Positioning of Ships in Extreme Seas
(Master thesis, 2015)The primary purpose of this study is to develop two different dynamic position- ing (DP) controllers for a model-scale supply vessel Cybership III, and determine which control strategy provides a safer, smarter and greener ... -
Comparing Controllers for Dynamic Positioning of Ships in Extreme Seas
(Journal article; Peer reviewed, 2016)This paper considers the design, implementation and experimental verification of two controllers for ship station keeping in extreme seas. In particular, the performance of two dynamic positioning controllers are compared, ... -
Comparing Deep Reinforcement Learning Algorithms’ Ability to Safely Navigate Challenging Waters
(Peer reviewed; Journal article, 2021)Reinforcement Learning (RL) controllers have proved to effectively tackle the dual objectives of path following and collision avoidance. However, finding which RL algorithm setup optimally trades off these two tasks is not ... -
Comparing Filters for Correction of Second Order Diffraction Effects in Hyperspectral Imagers
(Journal article; Peer reviewed, 2023)Second order diffraction effects often occur in hyperspectral instruments with dispersive elements. These second (and higher) order diffractions are typically unwanted, and should therefore be removed. One way of achieving ... -
