The Adaptive Control Method for Preheating and Stretching Process of Geogrid

摘要

Preheating and stretching process is the key step of the product process of geogrid. To improve temperature control effect, a single parameter PID adaptive control algorithm is used in this article, which can easily be realized by software, and a temperature-speed double control system is brought in which based on the temperature-speed relation in the process of stretching. The temperature and speed can be kept at a best joint point by the way of adjusting the temperature and speed automatically in this system. It can largely improve the stability of the system and the stretching speed.
