Abstract


The Coiler Is extremely important equipment , rolling mill production line performance a direct impact on the quality of the finished product and the production efficiency of the entire unit . Coiler high-performance research is an important task of the steel manufacturers around the world . The current state - of - the - art rolling equipment used by the domestic steel companies are foreign imports , and to really improve the design capacity of the domestic steel rolling equipment , must accelerate improvements in technology , which strip wandering servo system is one of the most important aspects of a . With the development of computer technology , the gradual improvement of the control theory and the theory and technology is widely applied to the coiling machine , so that the accuracy of the coiler action , the sensitivity can be greatly improved , and thus meet the modern and rolling continuous high efficiency of production requirements and the needs of the working environment . In this paper , a steel strip coiler for the study, to control the amount of lateral deviation of the strip coiling process with MATLAB coiler wandering electro-hydraulic servo system design and analysis , coiler for deviation control system using conventional PID control algorithm and conventional PID control is more difficult to find the optimal parameters . The paper presents the methods and techniques of genetic algorithm in MATLAB to design the PID . The design of PID controller based on genetic algorithms to achieve high performance coiling deviation control . In the Coiler EPC System for a comprehensive analysis on the basis of the system using Siemens S7-400 series PLC as a controller to achieve on-site control . Using the STEP7 software written the PID control variables , parameters table and PID control flowchart details of the PID control with PLC . The final paper to write the strip coiler the deviation control the part of the program , to achieve a the strip coiler deviation control system PLC control .
