On Modeling of a Ship Propulsion System for Control Purposes
(Master thesis, 2012)In this thesis a model of a ship propulsion system containing an engine, turbocharger, propeller and ship was constructed. The purpose of the model is to be used in controller design and testing. This is motivated by the ... -
On Multi-UAS Sea Ice Monitoring
(Doctoral theses at NTNU;2019:4, Doctoral thesis, 2019)Work in the polar regions of our planet is unavoidably linked with hazards such as drift ice. Increased presence, fueled by economic interests in the Arctic, has for several decades called for research in the field of ice ... -
On Nonlinear and Optimization-based Control of Fixed-Wing Unmanned Aerial Vehicles
(Doctoral theses at NTNU;2022:197, Doctoral thesis, 2022)Methods from linear control theory have a considerable share in the state-of-the-art toolbox for control systems engineers when designing autopilots for conventional passenger aircraft. Linear controllers have well-established ... -
On optimal ensemble learning using the concept of diversity and negative correlation
(Master thesis, 2019)Under et studie av et sett vinnende Kaggle-løsninger, ble det fastslått at det er et problem at de vinnende løsningene består av veldig store ansamlinger av klassifikatorer. Med dette som motivasjon ble det utført et studie ... -
On Orbital Stabilization as an alternative to Reference Tracking Control
(Chapter, 2020)With the purpose of highlighting the concept of orbital stabilization as an alternative to the reference tracking control methodology, this paper considers simple, informative examples in relation to motion control of an ... -
On Orbital Stabilization for Industrial Manipulators: Case Study in Evaluating Performances of Modified PD+ and Inverse Dynamics Controllers
(Journal article; Peer reviewed, 2017)Orbital stabilization is one of the available alternatives to the classical asymptotic stabilization, known as the reference tracking control, which is typically considered and implemented for controlling motions of ... -
On Robotic Assembly and Optimization-Based Control of Industrial Manipulators
(Doctoral theses at NTNU;2019:112, Doctoral thesis, 2019)Robotic manipulators are essential tools of industry. They are ubiquituous in modern factories, and they are starting to become more commonplace everywhere else. The trend in robotic manipulators is to move towards allowing ... -
On selection of controlled variables for robust reservoir management
(Journal article; Peer reviewed, 2016) -
On Shut-In Based Production Optimization of Shale-Gas Systems
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:285, Doctoral thesis, 2014)The use of shale gas as an energy resource has increased extensively over the last decade, with emerging new technologies causing shale gas to become the largest source of growth in the US natural-gas supply. Ecient ... -
On small satellites for oceanography: A survey
(Journal article, 2016)The recent explosive growth of small satellite operations driven primarily from an academic or pedagogical need, has demonstrated the viability of commercial-off-the-shelf technologies in space. They have also leveraged ... -
On the accuracy of gradient estimation in extremum-seeking control using small perturbations
(Journal article; Peer reviewed, 2018)In many extremum-seeking control methods, perturbations are added to the parameter signals to estimate derivatives of the objective function (that is, the steady-state parameter-to-performance map) in order to optimize the ... -
On the applicability of a perceptually driven generative-adversarial framework for super-resolution of wind fields in complex terrain
(Master thesis, 2020)Det har nylig blitt gjort store fremskritt innenfor datasyn for konstruksjon av høyoppløste bilder fra referansebilder med lav oppløsning ved å benytte høy-\\dimensjonale aktiveringer fra ``feature-extractors" for å danne ... -
On the Boundedness Property of the Inertia Matrix and Skew-Symmetric Property of the Coriolis Matrix for Vehicle-Manipulator Systems
(Journal article; Peer reviewed, 2012)This paper addresses the boundedness property of the inertia matrix and the skew-symmetric property of the Coriolis matrix for vehicle-manipulator systems. These properties are widely used in control theory and Lyapunov-based ... -
On the calibration and optical performance of a Hyperspectral Imager for drones and small satellites
(Doctoral theses at NTNU;2023:418, Doctoral thesis, 2023)English summary Hyperspectral Imagers (HSIs) are currently being developed for a range of applications. Among these are various forms of Earth observation from airborne platforms such as drones and small satellites. In ... -
On the Dynamics of Money Circulation, Creation and Debt – a Control Systems Approach
(Doctoral theses at NTNU;2018:304, Doctoral thesis, 2018)This thesis develops and explores a way of understanding a macroeconomy; as a set of "nodes" interconnected via a network of money flows. A metaphor for this is a body with a circulatory blood system, furnishing the different ... -
On the Equivalence and Impact on Stability of Impedance Modeling of Power Electronic Converters in Different Domains
(Journal article, 2017)Small-signal analysis of power electronic converters and systems is often carried out by impedance-based methods. At the core of these methods lies the impedance modeling, which can either be obtained through analytical ... -
On the globally exponentially convergent immersion and invariance speed observer for mechanical systems
(Journal article; Peer reviewed, 2017)In this article we present a reformulation of the invariance and immersion speed observer of Astolfi et al. as applied to mechanical systems with bounded inertia matrices. This is done to explore the possibility of its ... -
