用于火工品压制的伺服压力机控制系统

针对目前国内火工品生产过程中普遍使用的几种压药方式存在压力精度低、稳定性差等问题,设计1台整机防爆的精密电子伺服压机,并重点研究作为压机核心的控制系统的搭建和压力控制算法设计.基于某类火工品压药过程中的具体工艺要求及技术指标,确定该型号压机的整体结构及电气控制系统设计,结合压药过程中压力被控对象的特点,设计一种基于变速积分PID算法的压药压力控制方法,并进行压药过程实验.试验结果表明:该算法的压药压力控制效果明显优于经典PID算法,成功实现了压机有效工作区间内输出压力0.3%的技术要求.该防爆伺服压机已成功应用于我国某厂的火工品压制生产中.

Study on Servo Press Control System for Pressing of Initiating Explosive Device

Aiming at the low accuracy, poor stability and other problems of common use pressing modes in Chinese initiating explosive device manufacturing process, design an overall explosion-proof electronic servo press device, and focused on the building of control system and the design of pressure control algorithm. Based on the specific process requirements and technical specifications of a certain initiating explosive device pressing process, determined the overall structure and design of the electrical control system for the press, combined with pressure controlled target characteristics in the pressing process, designed a pressure control strategy which is based on the PID with variable speed integral, and carried out the pressing test. The results showed that the effect of the method in this paper is obviously better than the classical PID algorithm, output pressure in the effective working range successfully achieved the technical requirements which are forced accuracy of 0.3%, and the explosion-proof electronic servo press has been successfully used in the initiating explosive device pressing process of a Chinese factory.
