Abstract: Fault
detection and diagnosis for pneumatic system of automatic
production line are studied. An expert system using fuzzy-neural
network and pneumatic circuit fault diagnosis instrument are
designed. The mathematical model of various pneumatic faults and
experimental device are built. In the end, some experiments are
done, which shows that the expert system using fuzzy-neural
network can diagnose fast and truly fault of pneumatic circuit.
Key words: Pneumatic
assembly line Fuzzy-neural network fault diagnosis Fault
