Model-based optimal sensor placement approaches to fuel cell stack system fault diagnosis

Abstract

The problem of optimal sensor placement for FDI consists in d etermining the set of sensors that minimizes a pre-defined cost function satisfying at the same time a pre-established set of FDI specifications for a given set of faults. This paper recalls t hree model-based optimal sensor location approaches: an Incremental search, a Heuristic search and a Binary Integer Linear Programming (BILP) formulation. The main contribution of this paper is a compar ative study that addresses efficiency, flexibility and other issues. The performance of the approac hes is demonstrated by an application to a fuel cell stack system.
