21. Tools for Structured Matrix Computations : Stratifications and Coupled Sylvester Equations
Sammanfattning : Developing theory, algorithms, and software tools for analyzing matrix pencils whose matrices have various structures are contemporary research problems. Such matrices are often coming from discretizations of systems of differential-algebraic equations. LÄS MER
22. Modelling and Simulation of the Fifth-Generation District Heating and Cooling
Sammanfattning : District heating and cooling are efficient systems for distributing heat and cold in urban areas. They are a key solution for planning future urban energy-efficient systems due to their high potential for integrating renewable energy sources. LÄS MER
23. Algebraic Approaches to Normal Forms and Zero Dynamics
Sammanfattning : The normal form of affine state space systems has been extensively studied during the last decade and it has found several important applications. Two such applications are exact input-output linearization and sliding mode control. A property of affine nonlinear systems that is simple to compute given a normal form is the zero dynamics. LÄS MER
24. Dynamic Security Region Assessment
Sammanfattning : Among a wide variety of topics that are covered by Dynamic Security Assessment (DSA), maintaining synchronous operation and acceptable voltage profiles stand out. These two stability categories are mostly jeopardized in the seconds after a large contingency occurs. LÄS MER
25. 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
