However, the ocular of hydraulic systems working condition is bad. It is difficult to obtain the parameter of hydraulic system. The fault of hydraulic system has pilosity nature, uncertainty and disguise. The fault sign and the fault reason of hydraulic system have complex non-linear mapping relations, therefore it cannot use the simple functional relation to describe. This has brought the difficulty for the classics fault diagnosis technology. The intelligent diagnosis technology base on ANN and ES can solove the above problem well and the diagnosis result is more accurate and reliable.
