【摘要】：房地產(chǎn)行業(yè)和汽車行業(yè)的快速發(fā)展推動(dòng)了國(guó)內(nèi)外浮法玻璃的需求量。我國(guó)雖然擁有世界“三大浮法玻璃工藝”中的洛陽(yáng)玻璃,但是仍有相當(dāng)一部分的浮法玻璃生產(chǎn)線所采用的依舊是80年代的控制系統(tǒng),不但控制精度不高、玻璃的產(chǎn)量和質(zhì)量一般,而且能耗非常高。近幾年我國(guó)自動(dòng)化行業(yè)發(fā)展迅速,浮法玻璃生產(chǎn)線也逐漸在向大型化、智能化發(fā)展,先進(jìn)浮法玻璃熱端控制系統(tǒng)的研究意義重大。 本文首先分析了國(guó)內(nèi)外浮法玻璃熱端控制系統(tǒng)的發(fā)展現(xiàn)狀,根據(jù)浮法玻璃熱端控制系統(tǒng)的控制要求,使用西門子SIMATIC PCS7控制系統(tǒng)作為設(shè)計(jì)平臺(tái),對(duì)整個(gè)浮法玻璃熱端控制系統(tǒng)的硬件配置、系統(tǒng)架構(gòu)的配置、軟硬件實(shí)現(xiàn)以及控制策略做了詳細(xì)的設(shè)計(jì)。其中在浮法玻璃流道玻璃液溫度控制方面提出了采用先進(jìn)的內(nèi)�？刂撇呗赃M(jìn)行改進(jìn),并在MATLAB的SIMULINK平臺(tái)上進(jìn)行仿真,仿真結(jié)果驗(yàn)證此方案相比原控制策略有明顯的優(yōu)勢(shì),在以后的工程實(shí)踐當(dāng)中值得借鑒。
[Abstract]:The rapid development of real estate industry and automobile industry has promoted the demand of float glass at home and abroad. Although our country has the Luoyang glass in the "three big float glass technology" in the world, but there are still quite a few float glass production lines that still adopt the control system of the 1980s, not only the control precision is not high. The output and quality of glass is average, and the energy consumption is very high. In recent years, with the rapid development of automation industry in China, the production line of float glass is gradually developing to large and intelligent. It is of great significance to study the advanced hot end control system of float glass. This paper first analyzes the development of hot end control system of float glass at home and abroad. According to the control requirements of hot end control system of float glass, Siemens SIMATIC PCS7 control system is used as the design platform. The hardware configuration, system architecture configuration, hardware and software implementation and control strategy of the whole floating glass hot end control system are designed in detail. In the aspect of temperature control of glass liquid in float glass channel, advanced internal model control strategy is proposed and simulated on the SIMULINK platform of MATLAB. The simulation results show that this scheme has obvious advantages compared with the original control strategy. In the future engineering practice is worth learning.
