  1. 6. Contention-based Multiple Access Architectures for Networked Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Dawn Tilbury; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical engineering; Elektroteknik;

    Sammanfattning : Networked Control Systems (NCSs) use a wireless network for communication between sensors and controllers, and require a Medium Access Controller (MAC) to arbitrate access to the shared medium. Traditionally, a MAC for control systems is chosen primarily based on the delay it introduces in the closed loop. LÄS MER

  3. 7. State-based Channel Access for a Network of Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER

  5. 9. CMOS Parallel-Sampling Receivers

    Författare :Henrik Johansson; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : As the processing capacity of the microelectronic circuits increases, the demands on the interconnects will also increase. Hence, there is a need for higher bandwidth to the chips. This dissertation discusses the possibilities to improve the input data rate to CMOS integrated circuits, which is the most common integrated circuit technology today. LÄS MER

  7. 10. Conceptual information models to integrate data management in engineering simulation

    Författare :Henrik Johansson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : The focus of this thesis is how simulation information, described by conceptual information models, shall be managed to support the simulation tasks performed within a product development process when using virtual prototyping. It is shown that the ability to simulate performance and manufacturing makes new demands on existing development processes and recognised methodologies. LÄS MER
