  1. 1. 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. 3. Development of Methods for Analysis and Optimization of Complex Jet Engine Systems

    Författare :Tomas Grönstedt; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; optimal control; variable cycle engine; performance analysis; double bypass variable cycle engine; jet engine; BDF methods; selective bleed variable cycle engine; turbofan; ODAE;

    Sammanfattning : This thesis describes the development of GESTPAN (GEneral Stationary and Transient Propulsion ANalysis), a generalized system for the design, steady-state and transient simulation of gas turbine systems. Some of the main achievements in the thesis are related to the development of new algorithms or integration of existing numerics tailored to simplify the structure and use of generalized gas turbine simulation systems.

  5. 4. Estimation of Thrust and Health Parameters for Jet Engines

    Författare :Mattias Henriksson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Thrust estimation; Kalman filtering; Gas turbine performance estimation; Reduced order observers; Gas path analysis;

    Sammanfattning : An advanced turbofan engine control system would benefit from an accurate thrust and engine performance estimate. Unfortunately, there is to date no reliable in-flight thrust measurement sensors available. LÄS MER

  7. 5. Dynamic threshold generators for robust fault detection

    Författare :Michael Bask; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Detection of faults, such as clogged valves, broken bearings or biased sensors, has been brought more and more into focus during the last few decades. There are two main reasons why faults are important to detect at an early stage. LÄS MER
