The Study on Controlling the Position of Air Cylinder by Electropneumatic Proportional Valve

用电-气比例阀对气缸位置进行控制的探讨

The mathematical models of main elements in the electro-hydraulic position servo system of horizontal dispensing equipment, such as proportional flow valve, cartridge valve, servomotor, are established. The characteristics of main elements are analyzed, according to simulating results by using MATLAB/ Simulink software.

建立了水平分配器电液伺服系统的主要元件比例流量阀、方向插装阀和接力器的数学模型，通过MATLAB/Simulink软件对其进行动态仿真，分析它们的特性。

The results show that the new type of proportional direction valve is of good steady state control characteristics and equal displacement characteristics. The linearity of the control curve of the main spool displacement is well. However, there exists a certain neutral position control dead zone.

研究结果表明，新型比例方向阀的稳态特性和等位移特性良好，主阀芯位移控制曲线的线性度也较好，但有一定的中位控制死区。
