  1. 16. Synthesis of a Model-based Tire Slip Controller

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LMI; synthesis; hybrid; piecewise linear; ABS; PID;

    Sammanfattning : The Anti-lock Braking System (ABS) is an important component of a complex steering system for the modern car. In the latest generation of brake-by-wire systems, the performance requirements on the ABS have changed. The controllers have to be able to maintain a specified tire slip for each wheel during braking. LÄS MER

  3. 17. Nonlinear Control of Unmanned Aerial Vehicles : Systems With an Attitude

    Författare :Marcus Greiff; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Control; Lyapunov Methods; Aerospace; Aerial Vehicles; Output Feedback; Control Theory;

    Sammanfattning : This thesis deals with the general problem of controlling rigid-body systems through space, with a special focus on unmanned aerial vehicles (UAVs). Several promising UAV control algorithms have been developed over the past decades, enabling truly astounding feats of agility when combined with modern sensing technologies. LÄS MER

  4. 18. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

    Författare :Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

    Sammanfattning : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. LÄS MER

  5. 19. On H-infinity Control and Large-Scale Systems

    Författare :Carolina Bergeling; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity Control; Decentralized Control; Large-Scale Systems; Infinite-Dimensional Systems;

    Sammanfattning : 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. LÄS MER

  7. 20. On low order controller synthesis using rational constraints

    Författare :Daniel Ankelhed; Anders Hansson; Anders Helmersson; Anders Forsgren; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; H-infinity synthesis; Linear Matrix Inequalities; rank constraints; polynomial constraints; interior point methods; Automatic control; Reglerteknik;

    Sammanfattning : In order to design robust controllers, H-infinity synthesis is a common tool to use. The controllers that result from these algorithms are typically of very high order, which complicates implementation. LÄS MER
