Abstract: |
Accurate
modeling mechanisms play an important role in model-based diagnosis, and the
bond graph modeling language has proved to be helpful for this task. In this
paper we present an algorithm for automatically derive ARR-like structures,
possible conflicts, from the bond graph model of a system. The algorithm uses
tempo- ral causal graphs as an intermediate
structure to generate the set of possible conflicts. Performance of the algo- rithm for structural and
sensor faults is then studied. Fi- nally, we present another algorithm to automatically de-
rive temporal information in the fault signature matrix for the set of
possible conflicts, thus improving the isolation capabilities of the
approach. |
