Optimal Positioning of Snake Robots in Vortex Wakes using Extremum-Seeking Control.
(Peer reviewed; Journal article, 2023)In this paper we explore the optimal positioning of an underwater snake robot (USR) for energy harvesting in the wake of a bluff body. The USR and fluid are simulated jointly using a coupled vortex particle-mesh method and ... -
Optimal production and maintenance scheduling for a multiproduct batch plant considering degradation
(Peer reviewed; Journal article, 2020)Performance decay due to asset degradation is an important constraint in industrial production and therefore needs to be actively considered. This paper focuses on short-term scheduling for multiproduct batch processes ... -
Optimal Reservoir control using nonlinear MPC and ECLIPSE
(Master thesis, 2007)Recent years advances within well deployment and instrumentation technology offers huge potentials for increased oil recovery from reservoir production. Wells can now be equipped with controllable valves at reservoir depth, ... -
Optimal Shaping of the MMC Circulating Currents for Preventing AC-side Power Oscillations from Propagating into HVDC Grids
(Journal article; Peer reviewed, 2019)A constrained optimization problem based on the Lagrange multipliers method is formulated to derive the circulating current references of Modular Multilevel Converters (MMC) directly in abc coordinates. The resulting ... -
Optimal Sizing of Energy Storage Systems for Shipboard Applications
(Journal article; Peer reviewed, 2018)The recent worldwide effort on the environmental issue has led to new regulations on greenhouse gases emissions (GHG), both for land and marine applications. Nowadays, the extensive electrification of transportation systems ... -
Optimal Throwing Motion of Three-Link Underactuated Robot: A Study of Virtual Holonomic Constraints
(Master thesis, 2014)Control design for weakly or underactuated systems, i.e. more degrees of freedom than number of control inputs available, has proven to be much more complex than fully actuated due to the new constraints it impose. This ... -
Optimal Thrust Allocation for Dynamic Positioning Systems using Mixed Integer Linear Programming
(Master thesis, 2015)Thrust allocation is the part in a dynamic positioning system that is responsible for giving set-points to the different actuators on a vessel in order to track a desired generalized force, which is the set of surge, sway ... -
Optimal trajectory planning for robotized tiling of floors
(Master thesis, 2013)This thesis describes the strategy of a new approach for automated tilesetting currently under development by nLink AS in Sogndal. The main focus of the thesis is the development of an appropriate strategy for path planning ... -
Optimal Voltage Control of the Southern Norwegian Power Grid: Mixed Integer Nonlinear Programming (MINLP) for Control and Optimization of the High Voltage Southern Norwegian Power Grid
(Master thesis, 2011)This thesis contains the synthesis, analysis and simulation results of an automatic optimal voltage controller for the Southern Norwegian power grid. Currently the high voltage power grid is controlled manually by operators ... -
Optimal wrist prosthesis kinematics : three-dimensional rotation statistics and parameter estimation
(Doktoravhandlinger ved NTNU, 1503-8181; 133, Doctoral thesis, 2002)This thesis presents new theoretical results related to the statistical analysis of three-dimensional rotational data, as well as experimental results on the rotational kinematics of exoskeletal prosthetic wrist joints. The ... -
Optimalisering av LNG-verdikjeden
(Master thesis, 2007)Hovedmålet i hovedoppgaven er å utvikle en effektiv metode for å optimalisere driften av Statoils LNG anlegg ved uforutsette hendelser som forsinket skipsankomst og problemer med en produksjonsbrønn. -
Optimalisering av rognsorteringsmaskin
(Master thesis, 2008)Hensikten med denne oppgaven har vært å utvikle en ny algoritme for optimalisering av rognsorteringsmaskiner. Bakgrunn for valg av oppgave er at studenten har sett et forbedringspotensial og begrensninger i det eksisterende ... -
Optimering og design av kontroll-software for Schunk PG-070
(Master thesis, 2014)Oppgaven går hovedsakelig ut på å implementere en adaptiv kontroller til en Schunk PG-70 griper, for å kompensere for friksjonskrefter som oppstår på grunn av gir, støv og kontakt mellom materialer inne i griperen.En rask ... -
Optimization Algorithms for Short-Term Production Planning
(Master thesis, 2009)In an oil and gas production system, where wells are connected to manifolds with multiple pipelines, a complex optimization problem arises. The objective will typically be to maximize the oil production, while respecting ... -
