Abstract

The principle of neural network′s back-propagation algorithm(BP) was introduced

and BP algorithm′s application on the hydraulic system fault diagnosis of a cosmonautic launching tower rotary platform was studied.Combining with the structure feature and work principle of the hydraulic system

a fault diagnosis system based on BP neural network was established.The feasibility of the system was proved through the identification

emulation and experimentation of hydraulic system′s fault patterns.The system has been successfully applied to the hydraulic circuit′s fault diagnosis and identification of the hydraulic system of a cosmonautic launching tower rotary platform.
