  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; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [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 Scalable H-infinity Control

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

    Author : Carolina Lidström; Lunds universitet.; Lund University.; Lunds universitet.; Lund University.; [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

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

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Daniel Ankelhed; Linköpings universitet.; Linköpings universitet.; [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

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE
