  1. 1. Backstepping and control allocation with applications to flight control

    Författare :Ola Härkegård; Torkel Glad; Marc Bodson; Linköpings universitet; []
    Nyckelord :backstepping; control allocation; flight control; control theory; nonlinear control; reglerteknik; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : In this thesis we study a number of nonlinear control problems motivated by their appearance in flight control. The results are presented in a general framework and can also be applied to other areas. The two main topics are backstepping and control allocation. LÄS MER

  3. 2. Vehicle Dynamics Control for Rollover Prevention

    Författare :Brad Schofield; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Rollover Prevention; Control Allocation; Nonlinear Control; Convex Optimization; Vehicle Dynamics;

    Sammanfattning : Vehicle rollover accidents are a particularly dangerous form of road accident. Existing vehicle dynamics controllers primarily deal with yaw stability, and are of limited use for dealing with problems of roll instability. LÄS MER

  4. 3. Safe Distributed Control Allocation for Articulated Heavy Vehicles

    Författare :Umur Erdinc; Chalmers tekniska högskola; []

    Sammanfattning : The electrification of trucks is now followed by the electrification of trailers. Additionally, the maximum allowed length of vehicle combinations has been increased in many countries to enhance efficiency. LÄS MER

  5. 4. Model-Based Vehicle Dynamics Control for Active Safety

    Författare :Brad Schofield; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Control Allocation; Vehicle Dynamics Control; Friction Estimation; Model-Based Control Design;

    Sammanfattning : The functionality of modern automotive vehicles is becoming increasingly dependent on control systems. Active safety is an area in which control systems play a pivotal role. Currently, rule-based control algorithms are widespread throughout the automotive industry. LÄS MER

  7. 5. A Graphical Language for Batch Control

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Batch Recipes; Batch Processes; Sequential Control; Grafcet; Petri nets; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In this thesis a graphical language for sequential control is presented and its application to batch control is examined and discussed. The name of the language is Grafchart. Its main feature is that it makes it possible to express complicated control problems in a compact and intuitive manner. LÄS MER
