基于PLC的打包机电液控制系统

一种基于PLC的电液自动控制系统，采用了电液比例阀的双闭环控制系统。在打包机的位置控制中，按打包不同阶段，应用多种模式的控制方法，使系统在实际运行中稳定性好、可表性高、抗干扰强，从而获得良好的控制效果。

This paper introduces an electrohydraulic control system based on PLC. A double close - loop control system with electro - hydraulic proportional valve is adopted. According to the different stages of the baling press the multi - model control methods is to realize position control of the baling system. The system possesses a series of performances such as fine stability, high reliability and strong disturbance to achieve efficient control in the practice.
