Abstract :
Wavelet neural network model is established, a sensor-online fault diagnosis method based on this model is proposed, fault diagnosis of multi-sensor is realized through the establishment of the separate neural network prediction model of every sensor. Simulation experiments are carried out with a large number of sensor data of modern strip mill HAGC (Hydraulic Automatic Gauge Control) system, The feasibility of the method is verified.
