【摘要】：隨著現(xiàn)代化生產(chǎn)的不斷發(fā)展，，高質(zhì)量帶鋼的需求量不斷增加，研究提高帶鋼質(zhì)量的方法，已經(jīng)成為當(dāng)今帶鋼生產(chǎn)的一個熱點問題。然而傳統(tǒng)落后的人工包裝方式是提高鋼鐵產(chǎn)量的一個阻礙。這種生產(chǎn)需求與落后包裝方式的矛盾，促使現(xiàn)代全自動化打捆機逐漸成為鋼材生產(chǎn)線一個重要設(shè)備。因此研制更加適合鋼鐵生產(chǎn)線的包裝打捆機具有很大的現(xiàn)實經(jīng)濟意義。 本課題來源于實際工程項目，此臺打捆機為熱窄帶卷多卷打捆機可以一次對多卷窄帶卷一起進行打捆，是國內(nèi)第一臺具有此種打捆方式的打捆機。但此臺打捆機在現(xiàn)場調(diào)試中出現(xiàn)了問題：由于紅外線傳感器受到鋼卷溫度的影響，發(fā)送信號錯誤，使得打捆失敗。經(jīng)過分析，本文參考此臺打捆機的打捆工藝，設(shè)計了送帶長度液壓伺服控制系統(tǒng)和收帶鋼帶張緊力控制液壓伺服控制系統(tǒng)，并基于Matlab/Simulink軟件平臺針對打捆機的控制系統(tǒng)進行了建模仿真，并且詳細(xì)研究了管道長度及直徑、油液體積彈性模量系統(tǒng)參數(shù)對系統(tǒng)動態(tài)性能的影響。 為了尋求能夠?qū)崿F(xiàn)對送帶長度和鋼帶張緊力更好控制的控制策略，引進了模糊PID算法。模糊PID控制算法結(jié)合了模糊控制和PID控制這兩種控制策略的優(yōu)點：模糊控制動態(tài)性能好和PID控制靜態(tài)性能好。這種算法具有良好的自適應(yīng)性和魯棒性，并且具有參數(shù)自調(diào)整能力。該控制器在響應(yīng)性能和穩(wěn)定性上改善了傳統(tǒng)PID控制存在的問題，提高了打捆機控制系統(tǒng)的動態(tài)性能。本文基于Matlab/Simulink仿真研究平臺校驗打捆機電液伺服控制系統(tǒng)的動態(tài)性能，對比驗證出模糊PID控制器對系統(tǒng)的控制效果更好。
[Abstract]:With the development of modern production, the demand for high quality strip has been increasing. The research of improving strip quality has become a hot issue in strip production. However, the traditional backwardness of artificial packing is an obstacle to improving steel production. The contradiction between the production demand and the backward packing mode makes the modern automatic binding machine become an important equipment of steel production line. Therefore, it is of great practical and economic significance to develop a packing and strapping machine which is more suitable for iron and steel production line. This subject comes from the actual project, this machine is a hot narrow tape coiling machine, which can be bundled together at a time. It is the first one in China with this kind of binding method. However, there are some problems in the field debugging of this strapping machine: due to the influence of the temperature of the steel coil, the infrared sensor sends the wrong signal, which makes the bundling fail. After analysis, the paper designs the hydraulic servo control system of the feeding length and the tension control hydraulic servo control system of the steel strip with reference to the binding technology of the strapping machine. Based on the Matlab/Simulink software platform, the control system of the strapping machine is modeled and simulated, and the influence of the length and diameter of the pipe and the parameters of the oil volume elastic modulus system on the dynamic performance of the system is studied in detail. Fuzzy PID algorithm is introduced in order to find a better control strategy for strip feeding length and strip tension. Fuzzy PID control algorithm combines the advantages of fuzzy control and PID control: fuzzy control has good dynamic performance and PID control has good static performance. This algorithm has good adaptability and robustness, and has the ability of parameter self-adjustment. The controller improves the performance and stability of the traditional PID control system and improves the dynamic performance of the control system. In this paper, the dynamic performance of the electro-hydraulic servo control system of the strapping machine is verified based on the Matlab/Simulink simulation platform, and it is verified that the fuzzy PID controller has better control effect on the system.
