【Abstract】 The mapping was described between the static ch ar acteristics and the state modular of electro-hydraulic servo valve. An intellige nt test system was developed and tested in basis of the modular identification f or BP nerve network,which can test the state characteristics of servo valve and to identify its state modular. The result shows that the method has better accur acy in fault model identification. It can form a check system which has self-lea rning, self-testing and intelligent diagnosis in combined with the test function of servo valve test-bed.更多还原
