  1. 1. Adaptiv reglering av system med glapp

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Mattias Grundelius; [1996]
    Nyckelord :Backlash; Limit Cycle; Phase Lead; Describing Function; Backlash Inverse; Model Reference Adaptive System; Recursive Least Square; Adaptive Control; Indirect Self Tuning Regulator; Object-Oriented Modeling; Technology and Engineering;

    Sammanfattning : Backlash is common in mechanical and hydraulic systems. It severely limits the overall system performance. Many mechanical solutions have been developed to overcome backlash, for example by using spring-loaded split gear assemblies or dual motor systems. LÄS MER

  3. 2. Introduction of Adaptive Active Filters in HVDC Systems

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Tor Göransson; [1993]
    Nyckelord :HVDC; Active fiters; Adaptive control; Parameter estimation; Technology and Engineering;

    Sammanfattning : When converting electric power from AC to DC, a 12-pulse converter is often used. Unfortunately, the converter creates harmonics superimposed on the DC voltage. These are removed by filters. A passive filter is normally used, but active filters may be added for improved performance. LÄS MER

  4. 3. Självinställare baserade på gradientmetoder

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Fred Andersson; Göran Lindh; [1982]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The report presents a scheme for self-tuning regulators based on gradient methods. The feasibility of the scheme is studied in some special cases. The scheme is used together with different estimation techniques such as extended least squares (ELS) method and indirect estimation using a one to one correspondance with the regulator parameters.
