本文介绍了液压同步控制实验台的基本组成及工作原理,重点采用主从控制的方式,针对极端负载下水平伺服油缸的同步控制精度进行了仿真研究。针对伺服比例阀、非对称伺服油缸建立了AMESim元件模型,在此基础上完成了阀控伺服油缸的闭环控制模型。最后通过实验不同的控制参数对系统的响应速度、准确性、稳定性等特性的影响,得出合理的PID控制参数。仿真结果表明,该控制系统能够满足所需的实验要求。

This paper introduces the composition and the working principle of hydraulic synchronous control test bench,the master-slave control method is used to simulation research on the synchronous control precision of the horizontal servo cylinder under extreme load.The Amesim component model is established for the servo proportional valve and the asymmetric servo cylinder.On this basis,the closed-loop control model of valve-controlled servo cylinder is completed.Finally,the influence of different control parameters on the response speed,accuracy and stability of the system are experimented,and reasonable PID control parameters are obtained.The simulation results show that the control system can meet the required experimental requirements.
