The Simulation Research On Electro-hydraulic Servo Control System Of HC Mill Intermediat Roller Move Transversely

In the rapid development of social and economic,the need of high qualitycold-rolled strip is increased.So the method to improve the quality of strip shape hasbecome one of the most important part in thin strip steel production,and theintermediate roller of HC mill move transversely is a form of important and effectivetechnology in controlling strip shape.In the process of rolling high precision thin stripsteel,if middle roller can realize online move transversely,there will be moreconducive to strip shape quality control,but there is still no complete theory toresearch the resistance of middle roller move transversely,in addition,the control ofintermediate roller move transversely is influenced largely by complicated loadinterference factors,which is the key difficult problem.In order to achieve reliablecontrol in intermediate roller online move transversely,usually to increase the systemcontrol stiffness,but it lead to a waste of energy consumption and higher investment inequipment.Using experimental method to rerearch the problem of load interferencenot only the investment and costs is higher,but also takes a long time.Based on thecontrol of intermediate roller online move transversely is facing the mechanical,electronic and liquid comprehensive control system in high precision strip shaperolling,and using each characteristic simulation platform softwares in allusion todifferent working conditions,by adopt joint simulation method may obtain the optimalsimulation performance,and then provide valuable reference for the engineeringpractice,which has important theoretical and practical significance.In order to simulate the working condition of intermediate in rolling process, thispaper use PROE and ADAMS established mechanical dynamics simulation model.And then basing on Simulink and AMEsim, considering their characteristics andadvantages,the simulation models of controller and hydraulic system isestablished.Finally, using the interface between softwares,the joint simulationplatform of the electro-hydraulic servo control system of HC mill intermediate rollermove transversely is established.Firstly,basing on the union simulation model theresistance of intermediate roller move transversely is acquired,and the range of the resistance of intermediate roller move transversely is analysed by combining themethod of theory and the exprimental result,and then the dynamics model is correctedon the basis of simulation resistance of intermediate roller move transversely.At last,the design parameters of hydraulic fluid simulation system is revised by using theresult of resistance range of intermediate roller move transversely,which is acquirtedfrom the simulation model,and then the final union simulation pattern of the wholesystem is built.In allusion to the problems of hard to contol and load interference effects seriousin the system of intermediate roller online move transversely,this paper designedauto-disturbances-rejection controller,and verified the function of the electro-hydraulic servo control system in the union simulation researchingplatform,contrasted and corroborated the ADRC control scheme is more feasible.
