  1. 11. Fault detection and model quality estimation using mixed integer linear programming

    Författare :Soheil Salehpour; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : Robustness is a necessary property of a control system in an industrial environment, due to changes of the process such as changes of material quality, aging of equipment, replacing of instrument, manual operation (e.g. a valve that is opened or closed) etc. LÄS MER

  3. 12. Toward Cyber-Secure and Resilient Networked Control Systems

    Författare :André Teixeira; Henrik Sandberg; Karl H. Johansson; Kameshwar Poolla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cyber Security; Resilience; Industrial Control Systems; Fault-Tolerant Systems; Risk Management; Cyber säkerhet; Resiliens; Industriella Styrsystem; Riskanalys; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Resilience is the ability to maintain acceptable levels of operation in the presence of abnormal conditions. It is an essential property in industrial control systems, which are the backbone of several critical infrastructures. LÄS MER

  4. 13. Distributed diagnosis and simulation based residual generators

    Författare :Jonas Biteus; Linköpings universitet; []
    Nyckelord :Diagnosis; Distributed diagnosis; Fault isolation; Residual generator; Simulation; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Fault diagnosis is becoming increasingly important for many technical systems. This is for example true in automotive vehicles where fault diagnosis is needed due to economic reasons such as efficient repair and fault prevention, and legislations that mainly deal with safety and pollution.

  5. 14. An Approach to Diagnosability Analysis for Interacting Finite State Systems

    Författare :Dan Lawesson; Ulf Nilsson; Inger Klein; Albert Benveniste; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Model-based diagnosis; abstraction; finite state systems; discrete event systems; Computer science; Datalogi;

    Sammanfattning : Fault isolation is the process of reasoning required to find the cause of a system failure. In a model-based approach, the available information is a model of the system and some observations. LÄS MER

  7. 15. A proposal for the diagnosis of uncertain dynamic systems based on interval models

    Författare :Esteban Gelso; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The performance of a model-based diagnosis system could be affected by several uncertainty sources, such as,model errors,uncertainty in measurements, and disturbances. This uncertainty can be handled by mean of interval models. LÄS MER
