Theory and Tools for Computer Aided Diagnosis Design- an Automotive Engine Use-Case Lecture with Erik Frisk
All dates for this event occur in the past.
To facilitate the use of advanced fault diagnosis analysis and design techniques to industrial sized systems, there is a need for computer support. With current trends in digitalization and data availability, there are also new possibilities in combining model-based techniques on-board the vehicle with off-board statistical analysis in a data center. For this purpose, a demo system based on simple and modern web-applications has been developed that implements this distributed scenario. In that context, this presentation will describe theory and tools suitable for a challenging industrial problem, air-path diagnosis in an automotive engine. Major design steps that will be illustrated are modelling, fault diagnosability analysis, residual generator analysis, test selection and code generation. The system is evaluated on measurements from our engine test-cell.
