  1. 16. Integrated Control and Real-Time Scheduling

    Författare :Anton Cervin; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; robotteknik; Automatiska system; reglerteknik; Automation; robotics; control engineering;

    Sammanfattning : The topic of the thesis is codesign of flexible real-time control systems. Integrating control theory and real-time scheduling theory, it is possible to achieve higher resource utilization and better control performance. The integration requires new tools for analysis, design, and implementation. LÄS MER

  3. 17. Active Engine Vibration Isolation using Feedback Control

    Författare :Claes Olsson; Ahmed El-Bahrawy; Lennart Ljung; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Broad band active vibration isolation of automobile engine using linear and nonlinear feedback control is considered. The objective is to reduce the forces transmitted to the chassis and body, and, thus, reducing vibrations and structure borne noise inside the vehicle compartment when the engine is subjected to different excitations.

  4. 18. Scheduling and Base-Station Cooperation in MIMO Downlink Systems

    Författare :Nima Seifi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Multiple input multiple output (MIMO) techniques have been shown to improvethe capacity and link reliability of wireless communication without a need to extrapower and bandwidth. In multi-user (MU) MIMO networks, a linear increaseof sum capacity in the number of transmit antennas can be achieved by usinglinear precoding combined with efficient scheduling algorithms. LÄS MER

  5. 19. Control and Communication-Schedule Co-design For Networked Control Systems

    Författare :Masoud Bahraini; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control; Networked Control Systems; Robust Invariance; Communication Scheduling;

    Sammanfattning : In a networked control system (NCS), the control loop is closed through a communication medium. This means that sensor measurements and/or control signals can be exchanged through a communication link. LÄS MER

  7. 20. Resource Allocation in Multi-Antenna Communication Systems with Limited Feedback

    Författare :David Hammarwall; Björn Ottersten; David Gesbert; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication; Telekommunikation;

    Sammanfattning : The use of multiple transmit antennas is considered a key ingredient to significantly improve the spectral efficiency of wireless communication systems beyond that of currently employed systems. Transmit beamforming schemes have been proposed to exploit the spatial characteristics of multi-antenna radio channels; that is, multiple-input single-output (MISO) channels. LÄS MER
