  1. 1. Parameter Estimation in Linear Descriptor Systems

    Författare :Markus Gerdin; Linköpings universitet; []
    Nyckelord :differential-algebraic equations; descriptor systems; identification; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differential-algebraic equations in the continuous-time case. LÄS MER

  3. 2. Some Results On Optimal Control for Nonlinear Descriptor Systems

    Författare :Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Descriptor Systems; Differential-Algebraic Systems; Controllability Function; Observability Function; Automatic control; Reglerteknik;

    Sammanfattning : I denna avhandling studeras optimal återkopplad styrning av olinjära deskriptorsystem. Ett deskriptorsystem är en matematisk beskrivning som kan innehålla både differentialekvationer och algebraiska ekvationer. LÄS MER

  4. 3. Diagnosability analysis and FDI system design for uncertain systems

    Författare :Daniel Eriksson; Erik Frisk; Mattias Krysander; Alexander Medvedev; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Our society depends on advanced and complex technical systems and machines, for example, cars for transportation, industrial robots in production lines, satellites for communication, and power plants for energy production. Consequences of a fault in such a system can be severe and result in human casualties, environmentally harmful emissions, high repair costs, or economical losses caused by unexpected stops in production lines.

  5. 4. Identification and Estimation for Models Described by Differential-Algebraic Equations

    Författare :Markus Gerdin; Torkel Glad; Lennart Ljung; Manfred Deistler; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-Algebraic Equations; Identifiability; Nonlinear systems; Modelling; Identification; Descriptor systems; Automatic control; Reglerteknik;

    Sammanfattning : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. LÄS MER

  7. 5. Ligand-based Methods for Data Management and Modelling

    Författare :Jonathan Alvarsson; Jarl E. S. Wikberg; Ola Spjuth; Claes Andersson; Martin Eklund; John P. Overington; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; QSAR; ligand-based drug discovery; bioclipse; information system; cheminformatics; bioinformatics; Farmaceutisk farmakologi; Pharmaceutical Pharmacology; Bioinformatik; Bioinformatics;

    Sammanfattning : Drug discovery is a complicated and expensive process in the billion dollar range. One way of making the drug development process more efficient is better information handling, modelling and visualisation. The majority of todays drugs are small molecules, which interact with drug targets to cause an effect. LÄS MER
