水平辊道式玻璃钢化炉及其温度控制系统研究

摘要

首先分析水平辊道式玻璃钢化生产线的构成与工艺流程,然后进行控制系统结构设计.钢化玻璃品质控制的关键在于温度控制,因为钢化玻璃电加热炉是一个非线性、时变、大滞后系统.在数学建模的基础上,将增益自适应补偿Smith 算法运用于电加热炉温度控制,取得比传统PID控制更优的控制效果.%This paper analyzes the composition and process of horizontal roller toughened glass production line firstly, then designs its control system. Temperature control is essential for quality control of toughened glass, because the electric heating toughened glass furnace is a nonlinear, time-varying and large delay system. After carrying out the mathematical model, the gain adaptive compensation Smith algorithm is used in electric oven temperature control, which has better control effect than traditional PID control.
