  1. 1. Investigating and Analyzing Jitter In Controller Area Network

    Kandidat-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Sandra Eriksen; Sissi Wilander; [2023]
    Nyckelord :Response Time Analysis; worst-case response-time; best-case response-time; jitter; Controller Area Network; CAN Bus; Real-time systems;

    Sammanfattning : Too large amount of jitter in a Controller Area Network in a vehcle can be very problematic since these systems are real-time embedded systems and therefore are time critical. It is a very important issue to investigate since message delays can be very catastrophic. LÄS MER

  3. 2. TSN Distributed Clock : An analysis of relationships between network configuration parameters and the resulting precision of time synchronization

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jakob Götberg; Jakob Olsson; [2023]
    Nyckelord :Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Real-time Communication; Time Sensitive Networking TSN ; IEEE 802.1AS; Ethernet; Time Aware Shaper TAS ; Realtids kommunikation;

    Sammanfattning : In real-time systems spanning a network, there is a need for deterministic communication. The best-effort approach which most of the Internets traffic follows is not suitable for this area since it does not guarantee packet delivery within a deadline and there is also no accurate measure of when the packet was sent.

  4. 3. Combining proprietary real-time Ethernet protocols with Time-Sensitive Networking for avionics : A simulation study in OMNeT++ with INET 4.4

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Fredrik Ekstedt Karpers; [2023]
    Nyckelord :Ethernet; Time-sensitivenetworking; Real-timenetworks; IEEE802.1Q; Aeronautics; OMNeT ; Ethernet; Time-sensitive networking; Realtidsnätverk; IEEE 802.1Q; Aeronautik; OMNeT ;

    Sammanfattning : Robust real-time communication is crucial in many safety-critical systems, such as air-crafts. One example of real-time communication within an aircraft is the Ethernet-based protocol called Proprietary Real-Time Ethernet (PRTE), used for sensor data and other hard real-time information exchange.

  5. 4. Diagnostics Framework for Time-Critical Control Systems in Cloud-Fog Automation

    Master-uppsats, Mälardalens universitet/Inbyggda system

    Författare :Johannes Deivard; Valentin Johansson; [2022]
    Nyckelord :Cloud-fog automation; distributed control systems; network diagnostics; process diagnostics; process mining; Industrial Internet of Things; Industry 4.0; network probing; wireless telecommunication; 5G; WiFi 6; eBPF;

    Sammanfattning : Evolving technology in wireless telecommunication, such as 5G, provides opportunities to utilize wireless communication more in an industrial setting where reliability and predictability are of great concern. More capable Industrial Internet of Things devices (IIoT) are, indeed, a catalyst for Industry 4.0. LÄS MER

  7. 5. Latency Aware and Event-Based Wireless Control for Cloud-Fog Automation

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Sofie Nilsson; Anna Bengtsson; [2022]
    Nyckelord :Wireless control; Cloud-fog automation; Latency; PID control; Event-based derivative control; Threshold tuning; Technology and Engineering;

    Sammanfattning : The development seen within industrial automation in recent years enables the emergence of manufacturing sites that utilise technology for improved productivity, quality and safety. Increased communication demands introduced by Industry 4. LÄS MER
