A virtual vertical reference concept for aided inertial navigation at the sea surface
(Journal article; Peer reviewed, 2017)When trying to capture the heaving motion of a marine vessel in waves, conventional position references such as global navigation satellite systems fall short in many cases. Because of design and satellite geometry, the ... -
Adaptive Feedforward Control of Exhaust Recirculation in Large Diesel Engines
(Journal article; Peer reviewed, 2017)Environmental concern has led the International Maritime Organization to restrict NO$_x$ emissions from marine diesel engines. Exhaust gas recirculation (EGR) systems have been introduced in order to comply to the new ... -
Boarding control system for improved accessibility to offshore wind turbines: Full-scale testing
(Journal article; Peer reviewed, 2015)This paper considers the dynamic modelling and motion control of a Surface Effect Ship (SES) for safer transfer of personnel and equipment from vessel to-and-from an offshore wind-turbine. The control system designed is ... -
Experimental validation of attitude and rate-sensor bias filter using range-difference measurements
(Peer reviewed; Journal article, 2018)This paper considers the problem of constructing a filter for estimating attitude and rate-sensor bias, that has both proven stability and close-to-optimal performance with respect to noise. The filter is based on measuring ... -
Improved oscillation detection via noise-assisted data analysis
(Journal article; Peer reviewed, 2018)Oscillation detection is usually a precursor to more advanced performance monitoring steps such as plant wide oscillation detection and root cause detection. Therefore any false or missed detection can have serious ... -
Incident detection and isolation in drilling using analytical redundancy relations
(Journal article; Peer reviewed, 2015-08)Early diagnosis of incidents that could delay or endanger a drilling operation for oil or gas is essential to limit field development costs. Warnings about downhole incidents should come early enough to allow intervention ... -
Mooring System Diagnosis and Structural Reliability Control for Position Moored Vessels
(Journal article; Peer reviewed, 2014)Early diagnosis and fault-tolerant control are essential for safe operation of floating platforms where mooring systems maintain vessel position and must withstand environmental loads. This paper considers two critical ... -
Nonlinear observer design for GNSS-aided inertial navigation systems with time-delayed GNSS measurements
(Journal article; Peer reviewed, 2017)Global navigation satellite system (GNSS) receivers suffer from an internal time-delay of up to several hundred milliseconds leading to a degeneration of position accuracy in high-dynamic systems. With the increasing ... -
Reinforcement learning-based NMPC for tracking control of ASVs: Theory and experiments
(Peer reviewed; Journal article, 2022)We present a reinforcement learning-based (RL) model predictive control (MPC) method for trajectory tracking of surface vessels. The proposed method uses an MPC controller in order to perform both trajectory tracking and ...
