On a hybrid approach to model learning applied to virtual flow metering
Hotvedt, Mathilde (Doctoral theses at NTNU;2022:165, Doctoral thesis, 2022)Process modeling using first-principle equations has existed for centuries as a methodology to represent and analyze real-world processes. In time with increasing computing power and sensor data availability, data-driven ... -
Optimal and Stable Production of High Pressure Steam
Kristoffersen, Torstein T (Master thesis, 2013)Steam delivery networks are large energy consuming processes and an important source of energy in many processing plants. These networks are often subject to large disturbances, which can lead to costly operating periods ... -
Optimal Comfort with Limited Power
Rødal, Mads Dyrlid (Master thesis, 2018)Electricity consumption is growing and with more efficient equipment introducing larger power peaks. Reducing the power peaks can substantially reduce the electricity expenses for a building. In 2015 it was presented that ... -
Optimal Thrust Allocation for Dynamic Positioning Systems using Mixed Integer Linear Programming
Erdal, Mads (Master thesis, 2015)Thrust allocation is the part in a dynamic positioning system that is responsible for giving set-points to the different actuators on a vessel in order to track a desired generalized force, which is the set of surge, sway ... -
Robust Adaptive Control of a Surface Vessel in Managed Ice Using Hybrid Position- and Force Control
Østhus, Vegar (Master thesis, 2014)Studies done in recent years have shown a signicant decline in the coverage of arctic sea ice. This trend has made the Arctic more accessible and has resulted in expanded naval activity in this region. Furthermore, an ... -
