11. On a learning system for industrial automation : Model-based control and diagnostics for decision support
Sammanfattning : Access to energy is fundamental to economic and technological advancement. Hence, the more the world develops, the greater the demand for energy becomes. Evidently, the production and consumption of energy alone account for more than 80% of global anthropogenic greenhouse gas (GHG) emissions. LÄS MER
12. Adaptive and model-based control in laminar boundary-layer flows
Sammanfattning : In boundary-layer flows it is possible to reduce the friction drag by breaking the path from laminar to turbulent state. In low turbulence environments, the laminar-to-turbulent transition is dominated by local flow instabilities – Tollmien-Schlichting (TS) waves – that exponentially grows while being con- vected by the flow and, eventually, lead to transition.

13. Model-based control and monitoring of the flotation process
Sammanfattning : In the mineral processing industry, flotation constitutes the most important technique for extraction of the valuable minerals from the ore. This process involves both chemical and physical parts, the theory of which are not yet completely understood. LÄS MER
14. Control of Nitrogen Removal in Activated Sludge Processes
Sammanfattning : More stringent requirements on nitrogen removal from wastewater are the motivation for this thesis. In order to improve treatment results and enhance cost-efficient operation of wastewater treatment plants, model based control strategies are presented. A Java based simulator for activated sludge processes (JASS) is presented. LÄS MER
15. Model-based leakage detection in a pressurized system
Sammanfattning : Fault detection and isolation is a potentially powerful tool for achieving security and effective maintenance in various types of processes. The motivation for performing leakage detection in the coal injection plant is mainly the inflammability of pulverized coal. A leakage of air into an injection vessel could have catastrophic consequences. LÄS MER
