塑料挤出机生产工艺参数调度优化专家系统

摘要

针对我国现阶段塑料挤出生产工艺的现状，提出基于专家系统的工艺参数优化方法来改造现有的控制系统。对专家系统的组成、人机接口、知识库的建立、推理机的设计和自学习机的设计等内容进行了介绍。利用专家系统程序设计语言Visual Prolog实现了塑料挤出机生产工艺参数配置专家系统，并输出了所需的工艺参数值，从而代替了操作工程师对塑料挤出生产工艺参数的手动设置，节约了人力成本，提高了自动化水平和生产效率。%This paper, according to China's current production of plastic extrusion, proposes the opti-mized process parameters based on expert system to retrofit the existing control system.It also introduces the composition of expert system, man-machine interface, the establishment of information base, the de-sign of inference machine and self-learning machine.By Visual Prolog, an expert system programmed language, the expert system configured with plastic extruder process parameters is finally realized with the required values of process parameters.Hence, it replaces the manual setting of process parameters by en-gineers, saves labor costs as well as improves automation and production efficiency.
