  1. 21. Flexible Embedded Control Systems : Design and Implementation

    Författare :Johan Eker; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Feedback scheduling; Quality of service; Linear quadratic control; Toolbox; Simulation; Rapid prototyping; Programming language; Scheduling; Embedded systems; Real-time system; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : Embedded control system design is a complex and error prone task, and there is a great need for better development tools. Today most real-time control systems are static systems, designed in an ad-hoc fashion. A more interactive way of working would give shorter development times, reduced costs for testing, and safer, more robust systems. LÄS MER

  3. 22. Modelling and Control Methods with Applications to Mechanical Waves

    Författare :Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Sammanfattning : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.

  4. 23. Underactuated mechanical systems : Contributions to trajectory planning, analysis, and control

    Författare :Pedro La Hera; Anton Shiriaev; Ambarish Goswami; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Underactuated mechanical systems; mechanical systems with impacts; trajectory planning; periodic trajectories; orbital stabilization; walking robots; virtual holonomic constraints; transverse linearization; Automatic control; Reglerteknik; Automatic Control; reglerteknik;

    Sammanfattning : Nature and its variety of motion forms have inspired new robot designs with inherentunderactuated dynamics. The fundamental characteristic of these controlled mechanicalsystems, called underactuated, is to have the number of actuators less than the number ofdegrees of freedom. LÄS MER

  5. 24. Nonlinear Control of Unmanned Aerial Vehicles : Systems With an Attitude

    Författare :Marcus Greiff; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear Control; Lyapunov Methods; Aerospace; Aerial Vehicles; Output Feedback; Control Theory;

    Sammanfattning : This thesis deals with the general problem of controlling rigid-body systems through space, with a special focus on unmanned aerial vehicles (UAVs). Several promising UAV control algorithms have been developed over the past decades, enabling truly astounding feats of agility when combined with modern sensing technologies. LÄS MER

  7. 25. Data-Rich Multivariable Control of Heavy-Duty Engines

    Författare :Maria Henningsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Multivariable Control; Model Predictive Control; LQG Control; Virtual Sensing; System Identification; Diesel engines; HCCI engines; Dual-Fuel Combustion; Cylinder Pressure Sensors;

    Sammanfattning : The combustion engine is today the dominant technology for transportation of goods and people world-wide. Concerns for global warming, toxic exhaust emissions, as well as cost and availability of fuel have in recent years created incentives for technological evolution of combustion engines. LÄS MER
