1. 1. Statistical Fault Detection with Applications to IMU Disturbances

   Författare :David Törnqvist; Fredrik Gustafsson; Alexander Medvedev; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault detection; Linear systems; State-space models; Signal processing; State estimation; Fault observability; Inertial Measurement Unit; Automatic control; Reglerteknik;

   Sammanfattning : This thesis deals with the problem of detecting faults in an environment where the measurements are affected by additive noise. To do this, a residual sensitive to faults is derived and statistical methods are used to distinguish faults from noise. LÄS MER

3. 2. Assessment and Comparison of Physical Fault Injection Techniques

   Författare :Peter Folkesson; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault tolerance; concurrent error detection; dependability; coverage; fault injection; experimental validation; boundary scan;

   Sammanfattning : This thesis deals with the problem of validating and estimating the effectiveness of error handling mechanisms in computer systems. The main contribution is an assessment of the effectiveness and usefulness of several physical fault injection techniques. LÄS MER

4. 3. On Fault Injection-Based Assessment of Safety-Critical Systems

   Författare :Daniel Skarin; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Transient Faults; Fault Injection; Error Detection and Recovery; Fault Tolerance; Embedded Control Systems;

   Sammanfattning : This thesis deals with techniques for designing and evaluating error detection and recovery mechanisms for computer systems. For the assessment of such systems, we describe a comprehensive fault injection tool that is capable of emulating the effects of hardware errors in microprocessors. LÄS MER

5. 4. Residual Generation Methods for Fault Diagnosis with Automotive Applications

   Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

   Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

7. 5. Application-level Chaos Engineering

   Författare :Long Zhang; Martin Monperrus; Benoit Baudry; Leon Moonen; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; fault injection; dynamic analysis; software resilience; chaos engineering; Datalogi; Computer Science;

   Sammanfattning : With the development of software techniques, software systems nowadays are becoming highly complex. In order to keep such systems as reliable as possible, developers need to design various error-handling mechanisms. LÄS MER
