摘　　要：为使电液控制系统可靠地工作,必须对其核心元件——电液伺服阀的数学模型有准确的了解。文章以电液伺服阀为研究对象,对脉冲法识别元件和系统的数学模型的理论和实践进行了探讨,并取得了识别成功,同时指出了脉冲法的使用前景。In order to make the electro-hydraulic control system work reliably,a full understanding of mathematical model in the core element——electro-hydraulic servo valve of this system must be gained.This paper introduces a practice that tests the electro-hydraulic servo valve by means of inputting pulse signals and determines the dynamic mathematical model according to the theory of identification.Then the application prospect of modeling with pulse principle has been pointed out.
