Control Engineering and Intelligent Systems Group (eXiT)
eXiT is a research group (GRCT 41) of the Universitat de Girona integrated by professors and phD. students of the Departament d'Electrōnica Informātica i Automātica . The research activity is developed in the Institut d'Informātica i Aplicacions . The eXiT group collaborates in innovation projects in the industry within the EASY Center (CIDEM/X-IT network) and the teaching capacity is developed in the IT Doctoral program (Dept. EIA / IGSOC).
eXiT group develops an active research in the field of process supervision with emphasis in the integration of methods and techniques to assess process behaviour from measurements and experience reuse based on the following main points:
- Case Based Diagnosis: Adaptation of Case Based Reasoning (CBR) methodology into the domain of dynamic process with emphasis on diagnosis. Definition of similarity criteria between signals. Reuse of past experiences.
- Multivariate statistical process control: adaptation of these formalisms to model, fault detection and diagnosis of batch process.
- Qualitative representation of trends: definition, formalization and development of numeric to qualitative interfaces. Representation of signals as sequences of episodes necessary to deal with knowledge based approaches.
- Knowledge discovering in data bases for situation assessment.
This research is clearly domain dependent. Nowadays, the activity is developed in the following domains:
- Chemical and petrochemical process
- Waste water treatment plants
- Electric Distribution System (Power Quality)
- Electronic Circuits
Other recent research interest is in the field of Remote and Virtual laboratories. This is motivated by the necessity of testing and comparing experiences in shared configurable process and the teaching activity of the group.
