摘　　要：电液位置伺服控制装置设计的重点和难点是建立电液位置伺服控制系统的数学模型和传递函数及开环增益系数的确定。通过设计一种数控机床工作台的电液位置伺服控制装置,对数学模型和传递函数的建立做了详细介绍,并在MATLAB环境下对电液伺服控制系统进行仿真,确定出使系统稳定的开环增益。同时应用频率响应法对电液伺服控制系统的性能进行分析,从而得到满足要求的可靠电液伺服系统参数和满足设计要求的稳定电液位置伺服控制装置。The focus and difficulty of electro-hydraulic position servo control system design are to establish its mathematical models and transfer function and to determine the open-loop gain coefficient. This paper designs a CNC machine tool table positioning servo electro-hydraulic control device, and introduces the mathematical models and the establishment of transfer function in detail, takes the simulation of electro-hydraulic servo control system under the circumstances of MATLAB to determine the stability of the system mission open-loop gain. At the same time, the application of frequency response on the performance of electro-hydraulic servo control system is analysed, which met the requirements of a reliable electro-hydraulic servo system parameters and meet the design requirements for the stability of electro-hydraulic position servo control device .
