摘要
在重新定义负载压力和负载流量的基础上,推导出了四通阀控非对称液压缸的传递函数,建立了电液比例位置控制系统的数学模型,并利用MATLAB对系统进行了校正,结合具体系统对其动态特性进行了仿真研究,仿真结果论证了系统数学模型的正确性。
Based on redefining load pressure and flux, the transfer function of asymmetrical hydraulic cylinder controlled by sym- metrical four-way valve was deduced, the mathematic model of electro-hydraulic proportional position-control system was established. The adjustment of control system was carried out by use of MATLAB. The dynamic characteristics of the model were simulated. The results of simulation prove correctness of the system mathematic model.
