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

    Author : Anders Blomqvist; Anders Lindquist; Giorgio Picci; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

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

    Author : Stefan Almér; Ulf Jönsson; Gilead Tadmor; KTH; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. On Cooperative Surveillance, Online Trajectory Planning and Observer Based Control

    Author : David A. Anisi; Xiaoming Hu; Randal Beard; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Surveillance Missions; Minimum-Time Surveillance; Unmanned Ground Vehicles; Connectivity Constraints; Combinatorial Optimization; Computational Optimal Control; Receding Horizon Control; Mission Uncertainty; Safety; Task Completion; Adaptive Grid Methods; Missile Guidance; Nonlinear Observer Design; Active Observers; Non--uniformly Observable Systems; Mobile Robotic Systems; Intrinsic Observers; Differential Geometric Methods; Euler-Lagrange Systems; Contraction Analysis.; Optimization; systems theory; Optimeringslära; systemteori; Applied mathematics; Tillämpad matematik;

    Abstract : The main body of this thesis consists of six appended papers. In the  first two, different  cooperative surveillance problems are considered. The second two consider different aspects of the trajectory planning problem, while the last two deal with observer design for mobile robotic and Euler-Lagrange systems respectively. READ MORE

  7. 5. Spectral Moment Problems : Generalizations, Implementation and Tuning

    Author : Enrico Avventi; Anders Lindquist; Giorgio Picci; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Optimization; systems theory; Optimeringslära; systemteori;

    Abstract : Spectral moment interpolation find application in a wide array of use cases: robust control, system identification, model reduction to name the most notable ones. This thesis aims to expand the theory of such methods in three different directions. The first main contribution concerns the practical applicability. READ MORE
