  1. 1. A convex optimization approach to complexity constrained analytic interpolation with applications to ARMA estimation and robust control

    Författare :Anders Blomqvist; Anders Lindquist; Giorgio Picci; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical optimization; systems theory; analytic interpolation; moment matching; Nevanlinna-Pick interpolation; spectral estimation; convex optimization; Optimeringslära; systemteori; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : Analytical interpolation theory has several applications in systems and control. In particular, solutions of low degree, or more generally of low complexity, are of special interest since they allow for synthesis of simpler systems. LÄS MER

    Sammanfattning : This thesis is divided into two main parts. The first part is an exposé of Niklas Luhmann’s comprehensive sociological systems theory. Systems theory is a theory focusing upon the distinction between system and environment. LÄS MER

  5. 4. Control and Analysis of Pulse-Modulated Systems

    Författare :Stefan Almér; Ulf Jönsson; Gilead Tadmor; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Pulse-width modulation; Periodic systems; Stability analysis; Harmonic analysis; Lyapunov methods; Dynamic phasors; Harmonic transfer function; Switched mode power converters; Sampled data modeling; H-infinity synthesis; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : The thesis consists of an introduction and four appended papers. In the introduction we give an overview of pulse-modulated systems and provide a few examples of such systems. Furthermore, we introduce the so-called dynamic phasor model which is used as a basis for analysis in two of the appended papers. LÄS MER
