Quaternion-Based Generalized Super-Twisting Algorithm for Spacecraft Attitude Control
(Peer reviewed; Journal article, 2020)A second-order sliding mode control, the generalized super-twisting algorithm (GSTA), is used for attitude control of a spacecraft actuated by reaction wheels for pointing and a slewing maneuver. Magnetorquers are used for ... -
Quay Contact Detection for Ships using Motion Sensors and Machine Learning
(Peer reviewed; Journal article, 2022)Detecting when and where contact with the quay appears is an important ability for ships undergoing a docking maneuver. The motion of the quay, environmental forces, and hydrodynamic effects caused by the interaction between ... -
Radar målfølging
(Master thesis, 2008)Kongsberg Defense & Aerospace (KDA) benytter radarer av typen phased array i deres luftvernsystemer. På bakgrunn av nødvendige egenskaper som elektronisk styring av radarstråle tas denne radartypen også i bruk i denne ... -
Radar-based Maritime Collision Avoidance using Dynamic Window
(Journal article; Peer reviewed, 2018)Collision avoidance systems are a key ingredient in developing autonomous surface vehicles (ASVs). Such systems require real-time information about the environment, which can be obtained from transponder-based systems or ... -
RAMARL: Robustness Analysis with Multi-Agent Reinforcement Learning - Robust Reasoning in Autonomous Cyber-Physical Systems
(Peer reviewed; Journal article, 2022)A key driver to offering smart services is an infrastructure of Cyber-Physical systems (CPS)s. By definition, CPSs are intertwined physical and computational components that integrate physical behaviour with computation. ... -
Range Anxiety Alleviation for Electric Vehicles using a Dual Extended Kalman Filter with a Nonlinear Battery Model
(Master thesis, 2017)The purpose of this thesis was to find a solution to combat range anxiety in electric vehicles (EV). Range anxiety was defined as the fear that the driver will not reach their destination and is a major barrier to increase ... -
Range-based Target Localization and Pursuit with Autonomous Vehicles: An Approach using Posterior CRLB and Model Predictive Control
(Peer reviewed; Journal article, 2020)We address the general problem of multiple target localization and pursuit using measurements of the ranges from the targets to a set of autonomous pursuing vehicles, referred to as trackers. We develop a general framework ... -
Rapid Detumbling of Satellites
(Master thesis, 2024)Den innledende fasen av attituderegulering av en satellitt er undersøkt, med høy initiell vinkelfart. Målet med denne fasen er å redusere vinkelfarten slik at attituderegulering kan begynne, denne prosessen blir kalt ... -
Rare event chance-constrained optimal control using polynomial chaos and subset simulation
(Journal article; Peer reviewed, 2019)This study develops a chance–constrained open–loop optimal control (CC–OC) framework capable of handling rare event probabilities. Therefore, the framework uses the generalized polynomial chaos (gPC) method to calculate ... -
Reactive Collision Avoidance - Safe navigation in a dynamic cluttered environment
(Master thesis, 2018)Collision-free navigation in unknown environments is an essential quality for any autonomous vehicle. In this thesis, a reactive collision avoidance algorithm is presented for vehicles constrained by a unicycle nonholonomic ... -
Reactive Collision Avoidance for Nonholonomic Vehicles in Dynamic Environments with Obstacles of Arbitrary Shape
(Peer reviewed; Journal article, 2021)Over the recent years, there has been an increasing interest in autonomous systems. Consequently, the problem of avoiding static and dynamic obstacles without human interference has gained a lot of attention. Avoiding ... -
