吹塑机自动厚度控制系统设计

Automatic Gauge Control System for Blown Film Line

分析吹塑机厚度控制的原理和控制要求,根据自动模头厚度控制的特点,阐述通过工业计算机实现自动厚度控制的系统构成、算法和软件设计。介绍模糊-PID控制算法在系统中的应用。通过实践证明,采用模糊-PID控制算法控制反应速度快,系统稳定,控制精度高,比单一控制方式具有更好地控制性能。

This paper analyse working principle and control requirement of gauge control system,explain system construction,calculation and software design by industrial computer on the basis of gauge control characteristics of automatic die head,and introduces the application of Fuzzy-PID control calculation in the system which is proved to be fast and precise control with stable system and better property than single-way control.
