【摘要】：科學(xué)技術(shù)的不斷進(jìn)步,推動著工業(yè)技術(shù)的發(fā)展。隨著技術(shù)的不斷發(fā)展與創(chuàng)新,越來越多高性能的產(chǎn)品被制造出來。然而對新產(chǎn)品的研發(fā)和技術(shù)理論的深入創(chuàng)新研究往往需要投入巨大的費(fèi)用,而且有時存在無法避免的資源浪費(fèi)情況,因此,研究設(shè)計模擬系統(tǒng)得到人們的重視。工業(yè)領(lǐng)域模擬實驗平臺的研究主要集中在負(fù)載模擬器的研究,它是一種對實際工業(yè)現(xiàn)場中的各種負(fù)載進(jìn)行精確模擬的系統(tǒng)。本文研究與設(shè)計的卷取負(fù)載模擬器的主要目的是模擬實際卷取控制過程,使得研究設(shè)計人員可以方便地獲取大量的實驗數(shù)據(jù),為研究設(shè)計新的卷取控制系統(tǒng)提供試驗平臺,并且減少研究成本,提高研究效率。本文設(shè)計的卷取負(fù)載模擬器主要是對熱軋生產(chǎn)線卷取控制過程的模擬,因此設(shè)計了基于西門子運(yùn)動控制器SIMOTIOND的卷取張力控制系統(tǒng)和基于STM32系列單片機(jī)的負(fù)載模擬系統(tǒng)。卷取張力控制系統(tǒng)SIMOTIOND控制S120變頻器驅(qū)動永磁同步電機(jī)實現(xiàn)卷取控制功能;負(fù)載模擬系統(tǒng)采用有源逆變的方式產(chǎn)生負(fù)載電流,并且基于PI控制算法實現(xiàn)對直流電機(jī)電樞電流的控制,模擬出卷取負(fù)載力矩,加載于作為模擬卷取電機(jī)的永磁同步電機(jī)上。本文首先對某鋼鐵廠的熱軋卷取生產(chǎn)線卷取工藝、卷取機(jī)控制過程和現(xiàn)場的實際數(shù)據(jù)進(jìn)行了分析,建立了卷取負(fù)載數(shù)學(xué)模型。其次,設(shè)計了卷取負(fù)載模擬器,包括基于西門子運(yùn)動控制器SIMOTIOND的卷取張力控制系統(tǒng)和基于STM32系列單片機(jī)的卷取負(fù)載模擬系統(tǒng)。接著,對負(fù)載模擬系統(tǒng)控制板硬件進(jìn)行了設(shè)計,并對基于PI控制算法的電流調(diào)節(jié)器軟件做了設(shè)計。最后,負(fù)載模擬器試驗,完成對本文設(shè)計的卷取負(fù)載模擬器的驗證。結(jié)果表明本文設(shè)計的卷取負(fù)載模擬器不僅能夠?qū)崿F(xiàn)對卷取負(fù)載的模擬而且完成了恒張力卷取控制功能,為進(jìn)一步對卷取控制系統(tǒng)的研究與設(shè)計建立了良好的試驗基礎(chǔ)。
[Abstract]:The continuous progress of science and technology promotes the development of industrial technology. With the continuous development and innovation of technology, More and more high performance products are manufactured. However, the research and development of new products and the deep innovation of technology theory often cost a lot of money, and sometimes there is an unavoidable waste of resources. The research and design of simulation system has been paid more attention to. The research of simulation experiment platform in industrial field is mainly focused on the research of load simulator. It is a kind of accurate simulation system for various kinds of loads in the actual industrial field. The main purpose of this paper is to simulate the actual coiling control process, and the main purpose of this paper is to simulate the actual coiling control process. This makes it easy for the researchers to obtain a large amount of experimental data, provide a test platform for the research and design of a new coiling control system, and reduce the research cost. The coiling load simulator designed in this paper mainly simulates the coiling control process of hot rolling production line. Therefore, the coiling tension control system based on Siemens motion controller SIMOTIOND and the load simulation system based on STM32 series single chip microcomputer are designed. The coiling tension control system SIMOTIOND control S120 inverter drives permanent magnet synchronous motor to realize coiling control function. The load simulation system uses active inverter to generate load current, and realizes the control of armature current of DC motor based on Pi control algorithm, and simulates the coiling load moment. A permanent magnet synchronous motor (PMSM), which is used as an analog coiling motor, is loaded. Firstly, the coiling process of hot rolling coiling production line, the control process of coiler and the actual data on the spot are analyzed in this paper. The mathematical model of coiling load is established. Secondly, the coiling load simulator is designed, including the coiling tension control system based on Siemens motion controller SIMOTIOND and the coiling load simulation system based on STM32 series microcontroller. The hardware of the control board of the load simulation system is designed, and the current regulator software based on Pi control algorithm is designed. The results show that the coiling load simulator designed in this paper can not only simulate the coiling load but also realize the constant tension coiling control function. A good experimental foundation is established for further research and design of coiling control system.
