Control Model for Intelligent and Demand-Driven Supply Chains
(Chapter, 2011)Orchestrating supply chains is challenging. This chapter describes how to control a supply chain to make it truly demand-driven – based on the assumption that all relevant information is made available to all partners in ... -
Control of a Time-Variant 1–D Linear Hyperbolic PDE using Infinite-Dimensional Backstepping
(Journal article; Peer reviewed, 2018)We derive a state-feedback controller for a scalar 1-D linear hyperbolic partial differential equation (PDE) with a spatially-and time-varying interior-domain parameter. The resulting controller ensures convergence to zero ... -
Control of a Type-IV Wind Turbine with the Capability of Robust Grid-Synchronization and Inertial Response for Weak Grid Stable Operation
(Journal article; Peer reviewed, 2019)With the increasing penetration of wind power, the effective inertia of the power system reduces. Besides, a series of interactive instability issues including sub-synchronous oscillations and harmonic oscillations were ... -
Control of an End Body Towed by a Circling Unmanned Aerial Vehicle
(Journal article; Peer reviewed, 2019)The melting of the Arctic ice cap leads to increased commercial interest in these maritime regions, such as shipping via the Northeast Passage and oil and gas exploration, leading to a need to develop new long-range unmanned ... -
Control of conductivity and electric field induced strain in bulk Bi0.5K0.5TiO3-BiFeO3 ceramics
(Journal article; Peer reviewed, 2014)High electrical conductivity is one of the main obstacles for advances of bulk BiFeO3 ceramics in piezoelectric applications. Here, we demonstrate that the electrical conductivity of BiFeO3 can be lowered by compositional ... -
Control of DC-capacitor peak voltage in reduced capacitance single-phase STATCOM
(Chapter, 2016)This paper discusses the design and control of a single-phase STATCOM with reduced dc capacitance. It is first demonstrated how operation with reduced dc capacitance and large dc voltage oscillations can be possible without ... -
Control of Heat Pumps with CO2 Emission Intensity Forecasts
(Peer reviewed; Journal article, 2020)An optimized heat pump control for building heating was developed for minimizing CO 2 emissions from related electrical power generation. The control is using weather and CO 2 emission forecasts as inputs to a Model ... -
Control of heat transfer in single-story mechanically ventilated double skin facades
(Peer reviewed; Journal article, 2022)This paper systematically investigates and quantifies the interplay between mechanical ventilation rate and operation of venetian blinds in determining the performance of a single-story double skin façade. The investigation ... -
Control of HVDC systems based on diode rectifier for offshore wind farm applications
(Journal article; Peer reviewed, 2017)The transfer of energy from offshore wind farms using HVDC technology is highly dependant on the converter technology used. The conversion through HVDC has conventionally been done by Line Commutated Converters (LCC) or ... -
Control of magnetic states and spin interactions in bilayer CrCl3 with strain and electric fields: an ab initio study
(Peer reviewed; Journal article, 2023)Using ab initio density functional theory, we demonstrated the possibility of controlling the magnetic ground-state properties of bilayer CrCl3 by means of mechanical strains and electric fields. In principle, we investigated ... -
Control of power generated by a floating offshore wind turbine perturbed by sea waves
(Peer reviewed; Journal article, 2020)Offshore wind energy is expected to provide a signi cant contribution to the achievement of the European Renewable Energy targets. One of the main technological issues affecting oating offshore wind turbines con- cerns ... -
Control of Steady-state Gradient of an Ammonia Reactor using Transient Measurements
(Journal article; Peer reviewed, 2018)This paper presents the application of a steady-state real-time optimization strategy using transient measurements to an ammonia synthesis reactor case. We apply a new method for estimating the steady-state gradient of the ... -
Control of steam bottoming cycles using nonlinear input and output transformations for feedforward disturbance rejection
(Peer reviewed; Journal article, 2022)In this paper we analyze the control problem for a steam cycle that produces power by recovering waste-heat from gas turbines on an offshore installation. The waste-heat recovery unit is based on once-through steam generator ... -
Control of the combustion process and emission formation in marine gas engines
(Journal article; Peer reviewed, 2018)A smooth transition to the use of gas engines instead of conventional engines in marine shipping is a logical pathway for compliance with tightening environmental regulations. Currently, five major gas engine concepts are ... -
Control of Upper Limb Prostheses: Terminology and Proportional Myoelectric Control-A Review
(Journal article; Peer reviewed, 2012)The recent introduction of novel multifunction hands as well as new control paradigms increase the demand for advanced prosthetic control systems. In this context, an unambiguous terminology and a good understanding of the ... -
