Abstract: A new theory-the fuzzy
probability logic theory is presented. This theory incorporates
the genterally-used fuzzy logic and the traditionally-used
probability logic theory in attempt to emulate the rational
fault diagnosis under uncertainty. According to the theory, an
inference model, named as FSL, is thus designed to be devoted to
the building of a fault diagnosis expert system for rotating
machinery (ROSLES). The system is put into operation on a
vibration simulator stand for 300 MW turbine generator set
(1: 10) and satisfactory results are gained.
Key words:
Expert system Fault diagnosis
