The test data of the tested electro-hydraulic servo valve’s frequency characteristics are input to the microcomputer, and the mathematical model of the tested valve is conveniently obtained by using the identification function of the transfer function to form a complete new system for dynamic testing and microcomputer identification modeling, which is “Electro-hydraulic servo valve frequency characteristics of the test system and model identification” of the basic content.Compared with the existing state of the art, the scientific research has the main features and innovations are: First, not only to obtain the frequency characteristic curve, but also can Get the mathematical model of parameters; Second, we can get a model of each specific valve; Third, with 16k capacity microcomputer to complete the auxiliary test. The main technical indicators of the results in the leading position in the country by
