  4. 4. Flexible Embedded Control Systems : Design and Implementation

    Detta är en avhandling från Department of Automatic Control, Lund Institute of Technology (LTH)

    Författare :Johan Eker; Lunds universitet.; Lund University.; [1999]
    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

  5. 5. Control and Estimation of Automotive Powertrains with Backlash

    Detta är en avhandling från Göteborg : Department of Signals and Systems, Chalmers University of Technology

    Författare :Adam Lagerberg; Högskolan i Jönköping.; [2004]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Automatic control; TEKNIKVETENSKAP Informationsteknik Reglerteknik; backlash control; powertrain control; driveability; backlash estimation; model predictive control; optimal control;

    Sammanfattning : In automotive powertrains, backlash causes problems with vehicle driveability, specifically at so called tip-in and tip-out maneuvers. These maneuvers may trigger phenomena known in the automotive industry as shunt and shuffle, which are partially caused by the backlash. LÄS MER
