  1. 1. On H-infinity Control and Large-Scale Systems

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Carolina Bergeling; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Abstract : In this thesis, a class of linear time-invariant systems is identified for which a particular type of H-infinity optimal control problem can be solved explicitly. It follows that the synthesized controller can be given on a simple explicit form. READ MORE

  2. 2. On design of low order H-infinity controllers

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Daniel Ankelhed; Anders Hansson; Anders Helmersson; Jakob Stoustrup; [2011]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity synthesis; linear systems; linear matrix inequalities; rank constraints; optimization; rational constraints; interior point methods; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik;

    Abstract : When designing controllers with robust performance and stabilization requirements, H-infinity synthesis is a common tool to use. These controllers are often obtained by solving mathematical optimization problems. The controllers that result from these algorithms are typically of very high order, which complicates implementation. READ MORE

  3. 3. On Scalable H-infinity Control

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Carolina Lidström; [2016-06-16]
    Keywords : ;

    Abstract : Many of the classical approaches to controller synthesis do not scale well for large and complex systems. This is mainly due to computational complexity and the lack of distributed structure in the resulting controllers. READ MORE
