  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

  3. 2. Optimization of Joint Cell, Channel and Power Allocation in Wireless Communication Networks

    Författare :Mikael Fallgren; Anders Forsgren; Zhi-Quan (Tom) Luo; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless multicell networks; Optimization; OFDMA; Shannon capacity; Complexity; NP-hard; Relays; Allocation problems; Heuristic algorithms;

    Sammanfattning : In this thesis we formulate joint cell, channel and power allocation problems within wireless communication networks. The objectives are to maximize the user with mini- mum data throughput (Shannon capacity) or to maximize the total system throughput, referred to as the max-min and max-sum problem respectively.

  4. 3. Rigid-Body Attitude Control and Related Topics

    Författare :Johan Markdahl; Xiaoming Hu; Bijoy Ghosh; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This dissertation explores aspects of control in rigid-body and robotic systems. The first and second paper analyze the attitude stabilization problem and its generalization to n-dimensional rigid bodies. LÄS MER

  5. 4. Self-organization and Intervention of Nonlinear Multi-agent Systems

    Författare :Yuecheng Yang; Xiaoming Hu; Torkel Glad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent system; linear system; nonlinear system; opinion dynamics; crowd dynamics; leader-follower based model; optimal control; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Sammanfattning : This dissertation concerns the self-organization behaviors in different types of multi-agent systems, and possible ways to apply interventions on top ofthat to achieve certain goals. A bounded confidence opinion dynamics modelis considered for the first two papers. LÄS MER

  7. 5. Relative Information Based Distributed Control for Intrinsic Formations of Reduced Attitudes

    Författare :Silun Zhang; Xiaoming Hu; Junfeng Wu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Attitude control; distributed control; formation control; nonlinear systems; Mathematics; Matematik;

    Sammanfattning : This dissertation concerns the formation problems for multiple reduced attitudes, which are extensively utilized in many pointing applications and under-actuated scenarios for attitude maneuvers. In contrast to most existing methodologies on formation control, the proposed method does not need to contain any formation errors in the protocol. LÄS MER
