  1. 11. Multivariable Frequency-Domain Identification of Industrial Robots

    Författare :Erik Wernholt; Svante Gunnarsson; Jan Swevers; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Frequency-domain identification; industrial robots; nonparametric identification; nonlinear gray-box identification; multivariable systems; closed-loop identification; Automatic control; Reglerteknik;

    Sammanfattning : Industrirobotar är idag en väsentlig del i tillverkningsindustrin där de bland annat används för att minska kostnader, öka produktivitet och kvalitet och ersätta människor i farliga eller slitsamma uppgifter. Höga krav på noggrannhet och snabbhet hos robotens rörelser innebär också höga krav på de matematiska modeller som ligger till grund för robotens styrsystem. LÄS MER

  3. 12. A Study in Jet Engine Control Control Structure Selection and Multivariable Design

    Författare :Melker Härefors; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CSD; multivariable control; gain-scheduling; modelling; jet engine; anti-windup; control structure design; H sub infinity control;

    Sammanfattning : Turbojet engines are becoming increasingly complex, with more control variables, to meet future demands on performance, fuel consumption and functionality. To utilise the potential of these engines, it is also necessary to use more advanced control concepts than conventionally used today. LÄS MER

  4. 13. Modeling and Control of Plate Mill Processes

    Författare :Lars Malcolm Pedersen; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatiska system; robotics; control engineering; Automation; Rolling Mill. Reheat Furnace. Modeling. Identification. Control.; robotteknik; reglerteknik;

    Sammanfattning : In this thesis two processes have been modeled and controlled, namely the plate thickness control and the slab temperature control. The classical solution for the thickness control problem can't handle asymmetric hardness variations and the estimation of the controlled output introduces stability problems. LÄS MER

  5. 14. On modeling and control of complex dynamic systems

    Författare :Limei Ding; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Nonlinear complex multi-input multi-output process is very troublesome to control. It is usually also ill-modeled. The problem of such process both in control and modeling requires a comprehensive utilization of various techniques. The thesis presents the methods for the modeling and control of complex systems.

  7. 15. On input design in system identification for control

    Författare :Märta Barenthin; Bo Wahlberg; Håkan Hjalmarsson; Torkel Glad; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Systemidentifiering; Automatic control; Reglerteknik;

    Sammanfattning : There are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation. LÄS MER
