21. Frequency Domain Identification of Continuous-Time Systems : Reconstruction and Robustness
Sammanfattning : Approaching parameter estimation from the discrete-time domain is the dominating paradigm in system identification. Identification of continuous-time models on the other hand is motivated by the fact that modelling of physical systems often take place in continuous-time. LÄS MER
22. Model Error Compensation in ODE and DAE Estimators : with Automotive Engine Applications
Sammanfattning : Control and diagnosis of complex systems demand accurate information of the system state to enable efficient control and to detect system malfunction. Physical sensors are expensive and some quantities are hard or even impossible to measure with physical sensors. This has made model-based estimation an attractive alternative. LÄS MER
23. Performance and Implementation Aspects of Nonlinear Filtering
Sammanfattning : I många fall är det viktigt att kunna få ut så mycket och så bra information som möjligt ur tillgängliga mätningar. Att utvinna information om till exempel position och hastighet hos ett flygplan kallas för filtrering. I det här fallet är positionen och hastigheten exempel på tillstånd hos flygplanet, som i sin tur är ett system. LÄS MER
24. Direct imaging of Stimulated Raman scattering : 3D spatial control and spatial generation
Sammanfattning : Stimulated Raman scattering (SRS) is a powerful imaging technique that has become popular during the last decades for its ability to image species specific in a sample with high accuracy. The purpose of this thesis is twofold. Firstly, to demonstrate 3D spatial control of where in the sample SRS is generated. LÄS MER
25. Biosensors and Automation for Bioprocess Monitoring and Control
Sammanfattning : Bioprocess monitoring and control is a complex task that needs rapid and reliable methods which are adaptable to continuous analysis. Process monitoring during fermentation is widely applicable in the field of pharmaceutical, food and beverages and wastewater treatment. LÄS MER
