Waypoint guidance control for underwater snake robots exposed to ocean currents
(Chapter, 2016)This paper presents a waypoint guidance strategy for underwater snake robots, which is an extension of the straight line path following controllers previously proposed by the authors. The proposed waypoint guidance control ... -
Waypoint guidance control of snake robots
(Journal article; Peer reviewed, 2011)This paper considers path following control of snake robots and has two contributions. The first contribution is a description of how a straight line path following controller previously proposed by the authors can be ... -
Waypoint-Following Guidance Based on Feasibility Algorithms
(Master thesis, 2011)Unmanned vehicles have become more applicable due to extended research and more advanced technology through the last decades. The vehicles are versatile, hence studying ocean floor and reconnaissance and surveillance are ... -
Weather optimal dynamic positioning of underactuated AUVs using output feedback control
(Journal article, 2006)In this paper we present an output feedback control system for dynamic positioning of underactuated AUVs. The control objective is to maintain a desired distance to the target while orienting the vehicle towards the target ... -
Weather-Optimal Positioning Control for Underactuated USVs
(Master thesis, 2010)This thesis considers the design and development of a weather optimal positioning control system which is implemented on a developed 6 degrees of freedom vessel model of a Viknes 830 augmented with actuator and environmental ... -

Wheel Slip Control in ABS Brakes using Gain Scheduled Optimal Control with Constraints
(Dr. ingeniøravhandling, 0809-103X; 2003:43, Doctoral thesis, 2003)In a conventional antilock brake system (ABS), the wheel slip will oscillate around a "critical slip" within some given thresholds. This oscillation will have as side effects a noticeable vibration for the driver and ... -
When is gray-box modeling advantageous for virtual flow metering?
(Peer reviewed; Journal article, 2022)Integration of physics and machine learning in virtual flow metering applications is known as gray-box modeling. The combination is believed to enhance multiphase flow rate predictions. However, the superiority of gray-box ... -
Whole-Body Motion Planning and Collision Avoidance for AIAUV
(Master thesis, 2022)Leddede, autonome undervannsroboter (AIAUVer) baner vei for økt optimalisering av varierte marine operasjoner og er spesielt egnet for operasjoner i områder med begrenset fremkommelighet. For å løse ulike operasjoner på ... -
Why intraperitoneal glucose sensing is sometimes surprisingly rapid and sometimes slow: A hypothesis
(Journal article; Peer reviewed, 2019)The artificial pancreas requires fast and reliable glucose measurements. The peritoneal space has shown promising results, and in one of our studies we detected glucose changes in the peritoneal space already at the same ... -
Wi-Fi based Telecommunication Infrastructure Delivered as a Service by UAV for Emergency Response
(Chapter, 2022)In this paper we discuss Wi-Fi and complementary technologies that can be used to mitigate telecommunication gaps in search and rescue (SAR) activities and during natural disaster (ND) response scenarios. We present and ... -
Wienerization Based Control of Nonlinear Systems
(Chapter, 2022)We present a novel model approximation scheme, named “wienerization”, of nonlinear time invariant systems that uses the systems' nonlinear equilibria maps as the static nonlinearities of Wiener models. We show conditions ... -
Wienerization of systems in nonlinear control canonical normal form
(Chapter, 2022)We extend the concept of model approximation via wienerization to systems in nonlinear control canonical normal form. We elaborate on the conditions for, and implications of, analytically separating nonlinear input affine ... -
WiMAX in Coastal Traffic and Performance Prediction in a Geographically Challenging Environment
(Master thesis, 2009)This thesis takes upon itself to describe the medium of the radio channel for a WiMAX installation in a difficult environment. Furthermore it investigates the possibility of modifying the WiMAX standard in order to increase ... -
Wind Estimation with Multirotor UAVs
(Peer reviewed; Journal article, 2022)Unmanned Aerial Vehicles (UAVs) have benefited from a tremendous increase in popularity over the past decade, which has inspired their application toward many novel and unique use cases. One of them is the use of UAVs in ... -
