Fault diagnosis modeling of rotating speed sway for avion engine based on Fuzzy Neural Network

Owing to human´s experiences being rarely applied in the traditional fault diagnosis procedure, a kind of fault diagnosis model of rotating speed sway is established based on Fuzzy Neural Network (FNN) for avion engine. The fault diagnosis model can simulate expert´s fault diagnosis procedure, and improve fault diagnosis performance of rotating speed sway for avion engine. The simulation results show that fault diagnosis model can absorb human´s experiences, and make accurate judgments, the trained FNN has the same performance, and has solve self-learning problem.
