Abstract :
In this paper three model-based Fault Detection and Isolation (FDI) approaches for Discrete Event Systems (DES) are evaluated. The considered approaches are the diagnoser approach, the templates approach and the residual approach. The investigated methods have different characteristics like timed/non-timed behavior and fault-free / faulty system models with important impacts on the model-building process and the respective effectiveness. By applying the three methods to the same benchmark system, their respective performances are analyzed in terms of fault detection and fault isolation ability, complexity of implementation and avoidance of false alarms.
