Observation of a class of disturbance in time series expansion for fractional order systems
(Journal article; Peer reviewed, 2014)This paper is concerned with the problem of designing disturbance observer for fractional order systems, of which the disturbance is in time series expansion. The stability of a special observer with the selected nonlinear ... -
Observation of intrinsically bright terrestrial gamma ray flashes from the Mediterranean basin
(Journal article; Peer reviewed, 2015) -
Observer-based H∞ control design for nonlinear networked control systems with limited information
(Journal article; Peer reviewed, 2013)This paper is concerned with the problem of designing a robust observer-based H∞ controller for discrete-time networked systems with limited information. An improved networked control system model is proposed and the effects ... -
Observer-based robust control for hydraulic velocity control system
(Journal article; Peer reviewed, 2013)This paper investigates the problems of robust stabilization and robust control for the secondary component speed control system with parameters uncertainty and load disturbance. The aim is to enhance the control performance ... -
Observer-based robust control for spacecraft rendezvous with thrust saturation
(Journal article; Peer reviewed, 2014)This paper proposes an observer-based robust guaranteed cost control method for thrust-limited rendezvous in near-circular orbits. Treating the noncircularity of the target orbit as a parametric uncertainty, a linearized ... -
Observer-based robust H∞ control for switched stochastic systems with time-varying delay
(Journal article; Peer reviewed, 2013)This paper investigates the problem of observer-based robust H ∞ control for a class of switched stochastic systems with time-varying delay. Based on the average dwell time method, an exponential stability criterion for ... -
Observer-based sliding mode control for stabilization of a dynamic system with delayed output feedback
(Journal article; Peer reviewed, 2013)This paper considers the sliding mode control problem for a kind of dynamic delay system. First by utilizing Lyapunov stability theory and a linear matrix inequality technique, an observer based on delayed output feedback ... -
Observer-based stabilization of spacecraft rendezvous with variable sampling and sensor nonlinearity
(Journal article; Peer reviewed, 2013)This paper addresses the observer-based control problem of spacecraft rendezvous with nonuniform sampling period. The relative dynamic model is based on the classical Clohessy-Wiltshire equation, and sensor nonlinearity ... -
Observer-Based Stabilization of Stochastic Systems with Limited Communication
(Journal article; Peer reviewed, 2012)This paper studies the problem of observer-based stabilization of stochastic nonlinear systems with limited communication. A communication channel exists between the output of the plant and the input of the dynamic ... -
Offshore Wind Power Technology Development and Testing of a Downscaled Pitch Controlled Wind Turbine
(Master thesis, 2015)The energy demand of the world increases day by day, and at the same time people become more aware of the impact fossil energy sources have on the climate. This leads to an increased focus on renewable energy sources, ... -

Oil whip-induced wear in journal bearings
(Journal article; Peer reviewed, 2014)This paper investigates the effect of oil whirl and oil whip in fluid film radial bearings due to possible metallic contact. The degree of metallic contact and thereby wear and tear between rotating shafts and bearing ... -
Ombruk av hulldekker fra eksisterende bygg
(Master thesis, 2023)For a long time, the construction industry has been dominated by a linear mindset in building projects. The contemporary focus on our earth’s climate, has put pressure on the industry in regard to its relation for circular ... -

On break-away forces in actuated motion systems with nonlinear friction
(Journal article; Peer reviewed, 2017)The phenomenon of so-called break-away forces, as maximal actuation forces at which a sticking system begins to slide and thus passes over to a steady (macro) motion, is well known from the engineering practice but still ... -
On energy harvesting using piezoelectric transducer with two-port model under force excitation
(Chapter; Peer reviewed, 2019) -
On Stability of Virtual Torsion Sensor for Control of Flexible Robotic Joints with Hysteresis
(Journal article; Peer reviewed, 2019)Aim of the virtual torsion sensor (VTS) is in observing the nonlinear deflection in the flexible joints of robotic manipulators and, by its use, improving positioning control of the joint load. This model-based approach ... -
On stiffness and damping of vibro-impact dynamics of backlash
(Chapter, 2021)We consider the instantaneous stiffness and damping of the vibro-impact in a backlash pair. Opposed to the existing and mostly used models of the backlash, we address the problem of contact and separation, and the associated ... -
