Network design for distributed model-based fault detection and isolation

This paper addresses the design of the communication network topology of a distributed diagnosis system in order to improve the fault detection and isolation performances. Specifically, a binary integer liner programming (BILP) formulation is proposed to find the optimal combination of edges of a graph that leads to the best communication network in views of the distributed diagnosis system. The presented method is based on structural models where diagnosis properties can be easily obtained. In addition, the method is successfully applied on a four tank system as an illustrative example.
