Abstract


Continuous rolling process, rolling traffic between the rack is equal to the law to ensure that the tension between the rack , and therefore how to ensure a stable tension control of a continuous rolling process key technology . Based on a 1850mm double rack aluminum cold rolling mill in the background , for control of the many factors that influence the tension and to improve the stability of tension control , speed -depth research . This article first practical projects of 1850mm double rack strip rolling mill process and the control system has been described in detail, based on this study focuses on the tension control system are analyzed in detail by line . And units in the indirect tension control method are analyzed in detail , gives the diameter calculation and dynamic torque compensation formula. In the basic tension differential equations , considering rolling plastic compression deformation velocity changes , before sliding lag , lag , and so the motor speed response factors, the underlying tension differential has been improved . On this basis, derived multi-input , single-output dynamic mathematical model of tension control . According to the actual project using PI control methods for tension control simulation study, pointed out that the two-rack aluminum rolling mill for large-scale changes in tension of aluminum products , it is difficult for a stable tension control. For a particular pair of racks aluminum rolling mill tension control , we propose a control rate changes based on the controlled object parameter adaptive control strategy , the design of a fuzzy neural network adaptive PID controller . Implementation adopted at the absolute error function and maximum sensitivity constraints , through the calculation of pole placement controller parameters offline , online system parameters can be measured based on changes in real PID parameter modification method . Simulation results show that the control method has fast integer qualitative controller parameters , able to adapt to real-time two-rack aluminum rolling mill control requirements .
