1. Diagnosability performance analysis of models and fault detectors
Sammanfattning : Model-based diagnosis compares observations from a system with predictions using a mathematical model to detect and isolate faulty components. Analyzing which faults that can be detected and isolated given the model gives useful information when designing a diagnosis system. LÄS MER
2. Fault Isolation in Distributed Embedded Systems
Sammanfattning : To improve safety, reliability, and efficiency of automotive vehicles and other technical applications, embedded systems commonly use fault diagnosis consisting of fault detection and isolation. Since many systems are constructed as distributed embedded systems including multiple control units, it is necessary to perform global fault isolation using for example a central unit. LÄS MER
3. On Fault Detection, Diagnosis and Monitoring for Induction Motors
Sammanfattning : In this thesis, multiple methods and different approaches have been established and evaluated successfully, in order to detect and diagnose the faults of induction motors (IMs). The aim of this thesis is to present novel fault detection and isolation methods for the case of induction machines that would have the merit to be implemented online and being characterized by specific novel capabilities, when compared with the existing techniques.

4. A Bayesian approach to fault isolation with application to diesel engine diagnosis
Sammanfattning : Users of heavy trucks, as well as legislation, put increasing demands on heavy trucks. The vehicles should be more comfortable, reliable and safe. Furthermore, they should consume less fuel and be more environmentally friendly. For example, this means that faults that cause the emissions to increase must be detected early. LÄS MER
5. Fault detection and model quality estimation using mixed integer linear programming
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
