| Electro-hydraulic proportional control technology is a feasible technology whose control precision and response performance can satisfy with the practical requirements in the engineering. Electro-hydraulic proportional control system has advantages of both electricity and hydraulic technology, then having a strong function and potential and forming a competitive technical characteristic. Proportional unit do not need a high requirement of clearness of media but rather cheaper, and the static and dynamic responding supplied can meet the using requirements in most industrial fields.In this thesis, as electrolysis the anode plate mill headphone for the research object . Use of electro-hydraulic proportional direction valve designed the machine of electro-hydraulic proportional speed closed-loop control system. Completion of the anode plate positioning, compression, feeding and milling action. It mainly researches and analyses the vertical hydraulic slide feed control system. It proceeds to mathematical modeling for system components, discusses the fixed differential reducing valve and electro-hydraulic proportional direction valve combination function of analysis. Then establishes a mathematical model of hydraulic slide vertical feed control system.Analysis using MATLAB software, the system's static and dynamic performance of the system is designed with CtrlLAB corrector. AMEsim software with the basic hydraulic component library designed and built the pressure compensator and speed of the electro-hydraulic proportional control system simulation model. Design a fuzzy controller, with AMEsim / Matlab co-simulation, conventional PID control and fuzzy PID control of two controllers is compared results. The results show that the fuzzy PID controller improves the dynamic characteristics of the system to better meet production needs.
