Accounting for dynamics in self-optimizing control
Klemets, Jonatan Ralf Axel; Hovd, Morten (Journal article; Peer reviewed, 2019)Self-optimizing control focuses on minimizing the steady-state loss for processes in the presence of disturbances by holding selected controlled variables at constant set-points. The loss can further be reduced by controlling ... -
An ADMM algorithm for incorporating structural constraints in self-optimizing control
Klemets, Jonatan Ralf Axel; Hovd, Morten (Journal article; Peer reviewed, 2019)An ADMM algorithm is proposed for selecting structurally constrained measurement combinations as controlled variables (CVs). The CV selection is based on the self-optimizing control principle, where the goal is to choose ... -
An Iterative LMI Approach to Controller Design and Measurement Selection in Self-Optimizing Control
Klemets, Jonatan Ralf Axel; Hovd, Morten (Chapter, 2017)Self-optimizing control focuses on minimizing loss for processes in the presence of disturbances by holding selected controlled variables at constant set-points. The loss can further be reduced by controlling measurement ... -
Controller Design and Sparse Measurement Selection in Self-optimizing control
Klemets, Jonatan Ralf Axel; Hovd, Morten (Journal article; Peer reviewed, 2018)Self-optimizing control focuses on minimizing loss for processes in the presence of disturbances by holding selected controlled variables at constant set-points. A measurement combination can be found, using the Null-space ... -
Decentralized Energy Management Concept for Urban Charging Hubs with Multiple V2G Aggregators
Gümrükcü, Erdem; Klemets, Jonatan Ralf Axel; Suul, Jon Are Wold; Ponci, Ferdinanda; Monti, Antonello (Peer reviewed; Journal article, 2022)This work introduces a decentralized management concept for the urban charging hubs (UCHs) where electric vehicles (EVs) can access multiple charger clusters, each controlled by an aggregator. The given day ahead schedules ... -
Hierarchical Decentralized State Estimation With Unknown Correlation for Multiple and Partially Overlapping State Vectors
Klemets, Jonatan Ralf Axel; Hovd, Morten (Chapter, 2018)A fusion method for hierarchical decentralized state estimation is investigated with unknown cross-correlation. The process is divided into several local estimators for different subsystems that can operate independently ... -
Topics in the optimal operation of process plants
Klemets, Jonatan Ralf Axel (Doctoral theses at NTNU;2019:332, Doctoral thesis, 2019)An increasingly competitive global market, together with stricter environmental and safety regulations make it necessary for chemical process plants to operate close to its optimum. As a result, there has been a growing ... -
Voltage Support in Distribution Grids by Model Predictive Control of the Grid Interface Converter for a Battery Energy Storage System
Wøllo, Vebjørn (Master thesis, 2023)Elektrifiseringen av dagens samfunn og den økte mengden av distribuert energiproduksjon har ført til økt press på strømnettet. Dette presset kan resultere i utfordringer knyttet til nettstabilitet, spenningskvalitet og ...
