Control System Architecture for Automatic Recovery of Fixed-Wing Unmanned Aerial Vehicles in a Moving Arrest System
(Journal article; Peer reviewed, 2021)Automatic recovery is an important step in enabling fully autonomous missions using fixed-wing unmanned aerial vehicles (UAVs) operating from ships or other moving platforms. However, automatic recovery in moving arrest ... -
Control system design for concrete irrigation channels
(Chapter, 2017)Concrete channels find use at the periphery of irrigation networks, for expansion and to replace small earthen channels given the relative ease of maintenance and elimination of seepage losses. In design, it is important ... -
Control-oriented model of a generating set comprising a diesel engine and a synchronous generator
(Peer reviewed; Journal article, 2015)A generating set (Genset) comprises a prime mover such as a Diesel Engine, and a synchronous generator. The most important controllers of such systems are the speed governor to regulate the engine or shaft speed and the ... -
Control-Oriented Model of Molar Scavenge Oxygen Fraction for Exhaust Recirculation in Large Diesel Engines
(Journal article; Peer reviewed, 2016)Exhaust gas recirculation (EGR) systems have been introduced to large marine engines in order to reduce NO$_x$ formation. Adequate modelling for control design is one of the bottlenecks to design EGR control that also meets ... -
Control-relevant nonlinearity measure and integrated multi-model control
(Journal article; Peer reviewed, 2017)A control-relevant nonlinearity measure (CRNM) method is proposed based on the gap metric and the gap metric stability margin to measure the nonlinear degree of a system once a linear control strategy is selected. Supported ... -
Controllability analysis of planar snake robots influenced by viscous ground friction
(Chapter, 2009)This paper investigates the controllability properties of planar snake robots influenced by viscous ground friction forces. The paper provides three contributions: 1) A partially feedback linearized model of a planar snake ... -
Controllability and Stability Analysis of Planar Snake Robot Locomotion
(Journal article; Peer reviewed, 2011)This paper contributes to the understanding of snake robot locomotion by employing nonlinear system analysis tools for investigating fundamental properties of snake robot dynamics. The paper has five contributions: 1) a ... -
Controllable Enhancement of p-Wave Superconductivity via Magnetic Coupling to a Conventional Superconductor
(Peer reviewed; Journal article, 2021)Unconventional superconductors are of high interest due to their rich physics, a topical example being topological edge states associated with p-wave superconductivity. A practical obstacle in studying such systems is the ... -
Controllable spin-transfer torque on an antiferromagnet in a dual spin-valve
(Journal article; Peer reviewed, 2011)We consider current-induced spin-transfer torque on an antiferromagnet (AFM) in a dual spin-valve setup. It is demonstrated that a net magnetization may be induced in the AFM by partially or completely aligning the sublattice ... -
Controllable vortex loops in superconducting proximity systems
(Journal article; Peer reviewed, 2019)Superconducting vortex loops have so far avoided experimental detection despite being the focus of much theoretical work. We here propose a method of creating controllable vortex loops in the superconducting condensate ... -
Controlled Direct Liquid Cooling of Data Servers
(Journal article; Peer reviewed, 2020)We formulate a modeling and control framework aimed at direct liquid cooling of data servers. In our application scenario, the server's heat load is rejected into a liquid cooling circuit that extends to individual chips. ... -
Controlled doping of carbon catalyst supports by atomic replacement via gasification-assisted heteroatom doping
(Peer reviewed; Journal article, 2023)Due to a set of unique properties, carbon materials are applied as supports for metal-based catalysts in a wide variety of established and emerging (electro-)catalytical transformations. By introducing heteroatoms such as ... -
