  1. 6. Control of Systems with Limited Capacity

    Författare :Stefan Solyom; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; voltage collapse; power systems; anti-windup; piecewise linear systems; synthesis; ABS; PID control; LMI; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Virtually all real life systems are such that they present some kind of limitation on one or many of its variables, physical quantities. These systems are designated in this thesis as systems with limited capacity. This work is treating control related problems of a subclass of such systems, where the limitation is a critical factor.

    Författare :Daniel Simon; Johan Löfberg; Sébastien Gros; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control;

    Sammanfattning : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. LÄS MER

  4. 8. PID Control, Design, Extension, Application

Pulp and paper.; robotics; Automation; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : 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. LÄS MER

  5. 9. Identification, Diagnosis, and Control of a Flexible Robot Arm

    Författare :Måns Östring; Svante Gunnarsson; Mikael Norrlöf; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Identification; Robot; Flexible; Diagnosis; Control; LQG; Recursive;

    Sammanfattning : The most important factors in manufacturing are quality, cost, and productivity. The trend is towards lighter robots with increased mechanical flexibilities, and therefore there is a need to include the flexibilities in the robot models to obtain good performance of the robot.

  7. 10. Power System Oscillations - Detection, Estimation and Control

    Författare :Morten Hemmingsson; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. LÄS MER
