摘要
为了消除全液压驱动注塑机合模过程中较高的节流损耗并提高合模压力控制精确度,设计了注塑机合模过程电液伺服控制方案。基于注塑机合模过程的工作原理和结构特点,建立了其电液伺服系统的液压仿真模型和控制仿真模型,设计了参数自整定的模糊PID控制器,并进行了AMESim与Simulink联合仿真实验。实验结果表明,设计的合模过程伺服控制方案具有较好的压力稳态性能。
In order to eliminate the high throttling loss and improve the accuracy of hydraulic pressure control in the clamping process of injection machine driven by the whole hydraulic, the electro-hydraulic servo system of the injection molding machine is designed. Based on the working principle and structure characteristics of the injection molding machine＇s clamping process, the hydraulic simulation model and control simulation model of the electro-hydraulic servo system are established, the self-tuning fuzzy PID controller is designed, and AMESim/Simulink co-simulation experiments are carried on. The experimental results show that clamping hydraulic servo scheme of injection molding machine has a steady performance of the hydraulic pressure.
