Sensor Placement and Diagnosability
Résumé
Maintenance and diagnosis of complex systems are common activities in the industrial world. Technological advances have led to a continuously increasing complexity of industrial systems. This complexity, which is due to an increasing number of components reduces in turn the reliability of plants. Therefore, fault diagnosis is becoming a growing field of interest. But fault diagnosis relies on sensors: efficient fault diagnosis procedures require a relevant sensor placement. This paper presents a method for sensor placement based on diagnosability criteria. It makes it possible to determine a sensor placement, which satisfies diagnosability specifications. This method does not require the design of any analytical redundancy relation.
