摘　　要：系统辨识是通过试验来建立系统模型的一种归纳方法。本文利用频域辨识的基本原理,对电液伺服阀控液压缸系统及其主回路的数字模型（传递函数）建立,作了较详尽的理论分析和试验研究。通过对系统进行实测和计算机仿真,证实了所建立模型的可行性,并以此模型为基准,研究了系统的动态性能。System identification is a method of indu-ction for the creation of system models throu-gh experiments. A math model (transfer func-tion) of an electro- hydraulic servovalve-contr-ol-led cylinder system and its main circuit has been established by applying the basic princi-ple of frequency domain identifi-cation and its theoretical and experimental studies are dis-cusscd in detail. Through actual measurement and computer simulation, the method has been proven practical and can be used as the basis for dynamic performance study of the system.
