Electro-hydraulic servo mechanism health assessment method and system based on test data

The invention discloses an electro-hydraulic servo mechanism health assessment method and system based on test data. The method comprises the steps of obtaining a test data set which corresponds to a first time requirement; performing normalization quantization processing on all data in the test data set to obtain a second test set; obtaining parameter correction information according to all parameter information in the test data set; correcting all data in the second test set based on the parameter correction information to obtain a third test set; constructing a health evaluation model; inputting test data in the third test set and the predicted health evaluation rule into the health evaluation model to obtain a parameter evaluation set; and obtaining a health state evaluation result according to the parameter evaluation set. The technical problems that in the prior art, evaluation of the electro-hydraulic servo mechanism is phased, the evaluation result is non-type, and the dynamic development state of the
