  1. 1. Linear Model Predictive Control : Stability and Robustness

    Författare :Johan Löfberg; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Most real systems are subjected to constraints, both on the available control effort and the controlled variables. Classical linear feedback is in some cases not enough for such systems. This has motivated the development of a more complicated, nonlinear controller, called model predictive control, MPC. LÄS MER

  3. 2. Analysis and Design of Hybrid Systems

    Författare :Stefan Pettersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

    Sammanfattning : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. LÄS MER

  4. 3. Systems-level characterization of probiotic bifidobacteria - Towards rational optimization of industrial production

    Författare :Marie Schöpping; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; genome-scale metabolic modeling; stability; robustness; industrial manufacturing; bifidobacteria; stress-associated genes; probiotics; nutritional requirement; interspecies variations;

    Sammanfattning : Probiotic Bifidobacterium strains contribute to a healthy gut microbiota of their hosts. Increasing public awareness of this positive effect has resulted in a growing demand for these microorganisms. LÄS MER

  5. 4. Community Robustness Analysis : Theoretical Approaches to Identifying Keystone Structures in Ecological Communities

    Författare :Sofia Berg; Tomas Jonsson; Bo Ebenman; Daniel Stouffer; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Most of the world’s ecosystems suffer from stress caused by human activities such as habitat destruction, fragmentation, overexploitation of species and climate change. These factors affect the reproduction and/or survival of individual species as well as interactions between species in ecological communities. LÄS MER

  7. 5. Analytic Parameterization of Stabilizing Controllers for the Moore-Greitzer Compressor Model

    Författare :Alina Andersson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear control; Moore-Greitzer compressor model; Dynamic output feedback; Compressors; Nonlinear control systems; Stability robustness; Constraints; Nonlinearity; Lyapunov stability;

    Sammanfattning : This work presents an extension, simplification and application of a design procedure for dynamic output feedback design for systems with nonlinearities satisfying quadratic constraints (QC). Our method was motivated by the challenges of output feedback control design for the three-state Moore-Greitzer (MG) compressor model. LÄS MER
