摘　　要：该文对用传统的正弦信号输入法识别电液伺服阀动特性的理论和实践进行了探讨。设计了试验方案并编制了确定电液伺服阀数学模型的计算机拟合程序。通过辨识,对一般力反馈型两级电液伺服阀的合理的数学模型也进行了探讨。This paper introduces a practice that tests the two-stage force-feedback electro-hydraulic ser-vovalve by means of sinusoidal input signal, and then determines the dynamic mathematical model according to the theory of system identification. Moreover, the reasonable dynamic performances for this kind of valve are explored and a better researching result is obtained.
