Diagnosis and Sensor Placement for a Gas Lift Well
Authors: , , , ,
Abstract: A major contribution to supervision is to provide reliable diagnosis results reporting about the change of health status of the components of a system. An important related property, which allows one to provide guarantees about which faults are discriminable by the diagnoser, is diagnosability. Diagnosability analysis for production systems examines detectability (which faulty behaviors are discriminable from the normal behavior of the system) and isolability (which faulty behaviors are discriminable from which). Interestingly, diagnosability analysis provides the foundations for sensor placement, indicating parts of the system that suffer poor observability. In this paper, structural analysis is proposed as an efficient tool for diagnosability analysis and sensor placement, and applied to a real-world process of extraction of oil by gas injection.
