Fault Ride Through Capability Analysis of Small-Scale Hydro Power Plants
(Master thesis, 2016)This master thesis has looked upon the fault ride through capability assessment for small-scale hydro power plants in the distribution grid. In this report, the shape of the voltage dip has been studied, and the voltage ... -
Fault rock assemblages and fault architecture in the Møre-Trøndelag fault complex
(Master thesis, 2010)The Møre-Trøndelag Fault Complex (MTFC) is a major fault zone, extending along the coast of mid-Norway. It has a prolonged history of reactivation. Three outcrops along parts of the MTFC, known as the Tjellefonna Fault ... -
Fault scarp fan deltas, slope apron submarine fans and hanging-wall shallow marine sequences in the synrift Upper Jurassic Viking Group - Implications for reservoir characterization and geological modelling in the southern Halten Terrace, offshore Mid-Norway
(Master thesis, 2015)Thick synrift Upper Jurassic successions occurring in the vicinity of the recent Pil and Bue discovery wells in the southern Halten Terrace adjacent to the Vingleia Fault Complex represent submarine fans and fan-delta slope ... -
Fault Tolerant Control for automated Managed Pressure Drilling
(Master thesis, 2012)In the last years the cost for rig rental has become very high. To reduce total cost it has been necessary to increase the cost efficiency when drilling to improve profit. One way to improve profit is to reduce the ... -
Fault tolerant control of a proton exchange membrane fuel cell using Takagi–Sugeno virtual actuators
(Journal article, 2016)In this paper, a fault tolerant control (FTC) strategy for proton exchange membrane (PEM) fuel cells based on the use of virtual actuators and the Takagi–Sugeno (TS) approach is proposed. The overall solution relies on ... -

(Master thesis, 2015)This thesis fo cu ses on the fau lt-to lerant control al gor ithm o f the thr u ster-assiste d posi tio n moor ing system ( TAPM). TAPM is an energy-efficient and reliable stationkeeping method for deep water structures. ... -
Fault tolerant control of uncertain dynamical systems using interval virtual actuators
(Journal article; Peer reviewed, 2017)In this paper, a model reference fault tolerant control strategy based on a reconfiguration of the reference model, with the addition of a virtual actuator block, is presented for uncertain systems affected by disturbances ... -
Fault Tolerant Modular Multilevel Converter: Investigation of a New Method for Fault Tolerant Control
(Master thesis, 2014)In this thesis work, fault tolerant control and operation of a Modular Multilevel Converter (MMC) has been investigated. The MMC consists of multiple Sub Modules (SM). The MMC technology is rapidly evolving, and research ... -
Fault tolerant position mooring control based on structural reliability
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:156, Doctoral thesis, 2012)Safety of position mooring system is a prime concern in the marine industry and regulations are in force to prevent faults in equipment from causing failure of the whole system. There are many reasons for failures in ... -
Fault tree analysis applied to SIL (SAFETY INTEGRITY LEVEL)RATE SAFETY INSTRUMENTED SYSTEMS)
(Master thesis, 2010)This report is the documentation of an M.Sc. thesis carried out for the Technical Safetyand Reliability (TS & R) Group of FMC Technologies and the Department of Production and Quality Engineering, Norwegian University of ... -
Fault-sill interaction: Implications for magma routing and overburden faulting in the Vøring Basin, Norwegian North Sea.
(Master thesis, 2017)Magmatic sills in the study area are positive high amplitude anomalies with similar polarity as the seabed reflection. The sills have saucer, transgressive and concave-up geometries occurring at three principal stratigraphic ... -
Fault-tolerance for MPI Codes on Computational Clusters
(Master thesis, 2007)This thesis focuses on fault-tolerance for MPI codes on computational clusters. When an application runs on a very large cluster with thousands of processors, there is likely that a process crashes due to a hardware or ... -
Fault-tolerant control allocation for overactuated nonlinear systems
(Journal article; Peer reviewed, 2017)This paper addresses the problem of fault-tolerant control allocation for input affine nonlinear systems. The proposed scheme is divided in three main tasks: fault detection and estimation using a nonlinear observer, fault ... -
Fault-tolerant control allocation: an Unknown Input Observer based approach with constrained output fault directions
(Journal article; Peer reviewed, 2013)This paper focuses on the use of unknown input observers for detection and isolation of actuator and effector faults with control reconfiguration in overactuated systems. The control allocation actively uses input redundancy ... -
Fault-tolerant input allocation with actuator dynamics: finite-time control reconfiguration
(Journal article, 2014)This paper focuses on fault tolerant control allocation for overactuated systems with actuator dynamics. The proposed scheme for fault detection and isolation is based on unknown input observers and the main contribution ... -
Fault-tolerant Observer Design
(Master thesis, 2017)This master thesis dealt with the development of a fault-tolerant model-based observer for a low-cost ROV developed by BluEye Robotitcs, P2-Alpha. The observer was developed for 4 degrees of freedom (DOFs) using the installed ... -
